XPSemu (PPSA97358) imports eleven posix_spawn calls from libSceLibcInternal.prx, one reference each, and no call site is known. Predicted stop (import order, not measured), behind isnanf (idx 296): `FAIL: unresolved ELF import 44hlATrd47U from libSceLibcInternal.prx` (posix_spawnattr_init, idx 347), followed by p--TkNVsXjA, LG6O0oW9bQU, Sj7y+JO5PcM, Ud8CbISKRGM, Hq9-2AMG+ks, IUfBO5UIZNc, Heh4KJwyoX8 (348-355), UV4m0bznVtU, Ani6e+T-y6Q and 3Nr9caNHhyg (379-381). The nine object calls follow FreeBSD release/11.4.0 (8c639945a445) lib/libc/gen/posix_spawn.c: posix_spawnattr_init allocates a zeroed attribute object (ENOMEM on failure), _destroy frees it, _setflags and _setsigdefault store the value; posix_spawn_file_actions_init allocates an empty list (-1 on failure, as in 11.4), _destroy frees it with its entries, and _addopen (path copied), _adddup2 and _addclose append in order after returning EBADF for a negative descriptor. Null or uninitialized objects, which FreeBSD dereferences, throw. posix_spawn and posix_spawnp throw "process creation not implemented", as execvp does: FreeBSD validates no argument before rfork/vfork, and no child process can be created here. TechnicalDebt records them. guest_posix_spawn covers the attribute round trips, the recorded action sequence, the EBADF cases and the throws. NIDs computed with tools/nid_names.py and present in aerolib. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
