Segfault on 0x200[something] is correct segfault -- memory protection system, it should be continued. And you need build with debug symbols -- -g option.

[gregory]

The magic command on gdb is "handle SIGSEGV nostop" before running PCSX2. So you can run PCSX2 under gdb without press continue every 100ms

Most of the time, true segmentation fault will block the program. In case it does not stop, just CRTL-C before the crash (yes be fast) then restore default behavior with "handle SIGSEGV stop"

PS: if you do some debugs with GDB, you can encounter some Xorg freeze. Just use CTRL-ALT-F1, log and killall gdb.
