[Bug] [macOS] [ARM] PPU compile may hang with failure in memory_decommit on first load

[squidbus]

Quick summary

Sometimes when loading games with a fresh cache folder on an ARM Mac, the PPU compile will hang. Main game I use to reproduce this is Sonic Unleashed.

Details

When the compile hangs I usually see a few instances of this in the log:

F {PPUW.23.0} SIG: Thread terminated due to fatal error: Verification failed (object: 0x0)
(in file rpcs3/rpcs3/util/vm_native.cpp:348[:3], in function void utils::memory_decommit(void *, usz)) (errno=2=No such file or directory)

The compile also notably stops on the total number of modules minus the number of times that error occurs.

I still haven't encountered this one. When the objects are compiled it does "freeze" for about a minute the first run but then proceeds as usual. However, I'm still on 14.x so this may be an issue with MacOS itself changing behavior rather than rpcs3.

I don't actually seem to be able to reproduce this anymore for some reason, its possible another change somehow fixed it but I'm not sure what. Feel free to close if you want and I suppose if it comes up again someone will report it.

Closing as cannot reproduce. Request to reopen if the issue reappears.
