OK, I can try once more, perhaps the counter is much more then the
program expects (it resets when windows is restarted, here it counts up
from 1970/1/1). Try attached patch (first reverse previous patch, them
make; make install and test again)
Then if it does not work. As the patch fixes a real problem, reverting
is not an option. You will need to debug this to find out why the crash
If you run this with WINEDEBUG=+relay, can you look for both
QueryPerformanceCounter or QueryPerformanceFrequency in the lines just
before the crash?
With some luck the addresses of the call (look at ret=......) is near
where the crash happens ( it is reported by the debugger: 0x00500280)
and we can look at the disassembled code (debugger command
"disass adr1, addr2").
