AJM's instance and batch tables and APR's file, directory and AMM
state were namespace-scope statics, destroyed by std::exit while the
title's threads keep calling the libraries. A decoder thread then read
a freed instance (an unknown codec), sceAjmBatchWait no longer found
its batch, and APR resolved file ids through a freed vector. The state
is now allocated once and never destroyed.
As requested in review: a failed sceKernelGetModuleInfoFromAddr no longer
reports an empty answer. Adds a failure test (symbol interposition) and
extends the metadata test (EH record walk, terminator, no-header DSO).

A title that ships its own libc.prx unwinds C++ exceptions with that
libc's libunwind, which asks sceKernelGetModuleInfoForUnwind where each
frame's eh_frame is. On Linux the call always reported no tables, so
no C++ exception thrown in guest code could be caught. For the main
executable and .guest.prx images, report the PT_GNU_EH_FRAME tables
that sceKernelGetModuleInfoFromAddr finds, as Windows does from
.ehmeta. Other host images still report none.

Fill takes either info struct, so sceKernelGetModuleInfo reports the
name and segments sceKernelGetModuleInfoFromAddr reports for the same
image, on Linux and Windows.
sceKernelLoadStartModule discarded its arguments, and the relinker's Linux guest writer
synthesized an initialisation trampoline that also cleared the argument registers before
jumping to the module entry point, so a converted module always reached its own start-up
code with args = 0 and argp = NULL.
On PPSA28997 two of the title's own modules validate that parameter block as their first
act and dereference it unconditionally: SaveData faults on `mov (%rsi),%eax` with rsi = 0
beside its `cmp $0x10` size checks, and PSN faults the same way at PSN+0x3ee7 with rbx = 0.
The Windows branch delivers the block, so identical code reports its parameter-version
error and continues instead of faulting.
sceKernelLoadStartModule now records the pair before dlopen and clears it afterwards, and
the emitted DT_INIT stub reads it through two accessors exported by libkernel. The
initialiser is called rather than tail-jumped so its return value can be reported through
*res as the PS5 API specifies. The state is thread_local, which makes the handoff per-call:
ld.so runs a module's initialiser on the thread that called dlopen. DT_FINI keeps a plain
call-through, so unloading neither reads stale arguments nor reports a result.
The accessor names use the _nid_no_patch suffix so the NID resolver leaves them alone and a
guest import can name them exactly.
Retain host backing views for emulator writes and completion labels. Validate full spans, preserve write versions and GPU ordering, and keep the fallback for other mappings. Test remaps, aliases, access checks, partial failures, tracking, view lifetime, and completion ordering.
Written with AI assistance.
EVO-PLAYER (PPSA99039) v0.11.0 stops at sigaction once its earlier
imports resolve: it installs a crash handler for SIGSEGV, SIGBUS and
SIGABRT and a quit handler for SIGTERM, SIGINT and SIGHUP at start-up.
sigaction records the handler, flags and mask of signals 1 to 128 and
reports them back, with FreeBSD's EINVAL cases. signal shares the table
and records SA_RESTART, as FreeBSD's libc does. Plain handlers on the
signals signal already delivers run as signal handlers do; SA_SIGINFO
handlers and other signals are recorded only, and raise of such a
signal throws.

Each Windows AIO request is an overlapped ReadFile/WriteFile at the
request's offset, which on a synchronous handle also moves the
descriptor's file pointer; on the console AIO transfers leave it alone.
The requests now go through the positioned path sceKernelPread and
sceKernelPwrite use (NativePositioned in Stdio.cpp, exposed as
NativePositioned_nid_no_patch), which restores the pointer afterwards.
Negative offsets still fail with EINVAL before the transfer.
GuestAio sets the offset to 2 before a write batch and checks it is
still 2 after. TechnicalDebt records that a concurrent read or write on
the same descriptor can see the moved pointer in between, as for the
pread family.

Keeps both new TechnicalDebt entries: this branch's note that a raise
can still reenter host code it interrupted, and #2107's sigaltstack note.

msync follows FreeBSD 11's kern_msync and vm_map_sync over the guest's
mappings as sceKernelVirtualQuery reports them: the address is rounded
down to the page, a range that wraps and MS_ASYNC with MS_INVALIDATE are
EINVAL, an unmapped start or page is ENOMEM, and length 0 checks the
mapping that holds the address. The guest has no file mappings, so a
successful call has nothing to write back. MS_INVALIDATE on a mapped
range throws, since FreeBSD's EBUSY for mlocked pages needs lock state
that is not tracked.
EVO-PLAYER PPSA99039 v0.11.0 imports it.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.
