They probably forget to set PROT_EXEC in either mprotect or mmap somewhere.
You can check in /proc/*/maps which mapping contains the address it is
faulting on and then try to find where it is allocated or mprotect'ed.
Turned out this was exactly what the problem was. Wine attempts to match
Windows as far as read/write/execute mappings go, and war3.exe tried to
execute memory in a section with "MEM_EXECUTE" not set.
I'm surprised the program works on Windows with DEP/NX enabled, but apparently
it does.
Are you sure that it does? NX is not enabled by default on XP except on
Windows system processes, even on CPUs supporting hardware NX, so it
might well have failed with it turned on (especially since the problem
seemed to show up after some no-CD crack was applied).
