linux-wine used to segfault with:

$ /compat/linux/usr/bin/wineprefixcreate
fatal process exception: general protection fault, fault VA = 0x0 <- pid 1717?
fatal process exception: general protection fault, fault VA = 0x0 <- pid 1718?
Segmentation fault (core dumped)

under compat.linux.osrelease: 2.4.2, now linux-wine exits with:

$ /compat/linux/usr/bin/wineprefixcreate
wine: failed to initialize: /usr/lib/wine/ntdll.dll.so: failed to map
segment from shared object: Cannot allocate memory

Doesn't help the compat.linux.osrelease: 2.6.16 case, as it is a
different problem involving thread-local storage.

Thanks for the fix.
