OOM crash with 1.2.512 on Linux

[BaseOrion]

1.2.512 (on Linux) crashes for me with an out of memory error when starting a song. The "track" appears and just as the countdown is about to appear, it crashes.
I've got 540MB of free memory, that ought to be enough, I'd think...

Looks like GL3.0 is not stable with FoF, like Rogue_F said.
If you can make out some kind of memory manager, run FoF in a window and tell me how much memory it takes and how much spare RAM you have before it explodes.

[BaseOrion]

Right from the start, it uses around 170MB. When starting a song, the free memory quickly spirals down from ~330MB to 0, ~70MB get released (Python's garbage collector?), crash. The swap isn't touched at all.

[Rogue_F]

high memory use is usually a sign of not using pyogg for streaming the ogg files.

pygame can only stream 1 ogg at a time, the rest need to be fully loaded into memory. with a gh2 track with song, guitar, and rhythm, thatcan be a lot of memory used

I get this error immediately on startup in both 1.2.512 and 1.2.451.

Maybe you should add

Section "DRI"
Mode "666"
EndSection

into your xorg.conf?

Technically thats not a bug.
You need to delete your original version 1.2.512 ini
called "fretsonfire.ini" usually...
the thing is since its on Linux, I have no idea where that is.
