Looks like Armagetron Advanced or SDL is doing crazy stuff from a signal handler... My uneducated guess is that radeonFlush is triggering a SIGSEGV and libSDL is trying to shutdown sanely as a result, which creates a loop since the radeonFlush is already in the shutdown procedure. Can you get another backtrace showing what signal it is, with debugging symbols for at least r300_dri.so? Program received signal SIGSEGV, Segmentation fault.

ctx->DrawBuffer is a NULL pointer The classic r300 driver has been abandoned long ago. It was replaced by the Gallium driver r300g. If you have issues with r300g please file a new bug report with component Drivers/Gallium/r300 Thanks. |

If I press Shift-Esc while Armagetron Advanced is in a network-only state (fetching server list, between rounds, etc), the game locks up until I manually kill it (SIGINT works) --- Backtrace --- #0 0x00007ffb139827c4 in __lll_lock_wait () from /lib/libpthread.so.0 #1 0x00007ffb1397e029 in _L_lock_534 () from /lib/libpthread.so.0 #2 0x00007ffb1397de3e in pthread_mutex_lock () from /lib/libpthread.so.0 #3 0x00007ffb12e029dd in ??
