sceCoredumpAttachMemoryRegion and sceCoredumpAttachUserMemoryFile take
(uint32_t userValue, const void* mem, size_t size): the Orbital IDA type
database and the SharpProspero bindings agree on the first, the second
has only SharpProspero. Attaching belongs inside the core dump handler
the system runs after the process stops; a call from anywhere else gets
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER. The handler is never invoked
here, so every call returns that error and nothing is recorded. Whether
the console checks the region before the calling context is unknown, so
a null, empty or wrapping region throws.
The error value 0x81180003 is inferred from fpPS4's 0x81180001 and
0x81180002 and the numbering of the Vita's SceCoredump error table;
TechnicalDebt records the sources and what remains unverified.
guest_coredump_attach: the error before, during and after a handler
registration, from another thread too, without running the handler or
touching the region; null, empty and wrapping regions throw naming the
function.
