[BOX32] Box32 stopped working on Winlator

[alexvorxx]

Hi! Thank you very much for your work.

I used modified Winlator with Wine 9.2 bi-arch, tried to run wfm.exe (file manager).
Box32 does not work on Winlator starting from commit 3eeb10c.

Traces:
trace-23656-1.txt
trace-23670-1.txt

Also on the current box64 version reverting of 3eeb10c solves the problem.

maybe shmat function is not available on Winlator?

Yes, probably shmat is not available on Winlator. I see ashmemCreateRegion, memfd_create etc.

Maybe libandroid-shmem may help?

shmat is emulated in libandroid-sysvshm.so, but box32 does not work for some reason.
