By the way, after the crash occurs, maybe you can check the dmesg output and check the last few lines with tail command?

If the crash is being triggered due to incompatible driver, then check if there is an option in the fglrx drivers to log the errors. that might help.

@undeath: I like your first command line Smile

dmesg -> /var/log/kern.log shows this:
Code:
[  429.451697] oclHashcat-plus[2959]: segfault at 0 ip 00007f4f69f5f8c3 sp 00007fff1024ee08 error 6 in libc-2.15.so[7f4f69e10000+1b5000]

and with gdb we get this:
Code:
$ gdb oclHashcat-plus64.bin

It appears to be a libc issue. For those who can't reproduce, what's the glibc version you're running?
