ArchLinux(x64) - Crashing to desktop - SNES_SPC.cpp:497

[brachiation]

When running snes9x in linux (snes9x 1.53), I encounter what I believe to be a nasty segfault everytime I enter the first battle in Final Fantasy 6 (very easy to reproduce). I haven't tested many other games, but the same thing happens (with the same error exactly) in Chrono Trigger in some battles. These are the only games I tried, but the error output I get is this:

snes9x: ../apu/SNES_SPC.cpp:497: int SNES_SPC::cpu_read(int, SNES_SPC::rel_time_t): Assertion `reg + (r_t0out + 0xF0 - 0x10000) < 0x100' failed.
Aborted (core dumped)

I have tried muting the sound, using different video settings (opengl, software rendering), and whatever other settings I could change. Still the same problem. Does anyone have any ideas, or ways to try and fix this? I am afraid I suck at C++, so I wouldn't know how to debug the problem myself.
