Public bug reported:
This bug is quite intermittent but happens about 50% of the time. Once the game
is restarted after, all unlocked levels are relocked so I have only been able
to test it on the first few.
When starting a level (either directly from the main menu or by selecting next
level) the game routinely crashes (randomly but frequently).
When run using gdb a segmentation fault is detected and the system is locked
down (requiring ctrlaltsysrq k), The error message given is:
segfault 0xb7f177b1 in ov_raw_seek() /usr/lib/i386-linux-gnu/libvorbisfile.so.3
Unfortunately I wasn't given a chain of function calls or a line number as I'm
used to.
In the source; however, I only see this function called in
streamingoggsample.cpp as the restart function, which in turn is used in
audiobuffer.cpp in the getMix function and the Play function. The
prototype for the getMix function doesn't seem to match the way its used
in mixer::enqueueSample:
Sint16 *AudioBuffer::getMix(uint requested_length, uint &returned_length)
vs
uint l2;
Sint16 *b2 = audioBuffers[b].getMix(lsamples, l2);
Perhaps the latter should be getMix(lsamples, &l2);? Seems a likely cause for a
seg fault but then maybe it's my ignorance being more familiar with c.
I've got version 1.0.0~dfsg1-1 on Ubuntu 12.04. My CPU is a 64bit AMD.
I see no sign of the bug reported upstream. I am happy to pass it on if you
think its not a packaging issue.
