Some crashes seems to be related to libc6 around the following adress:
Program terminated with signal 11, Segmentation fault.
#0 0xf7572a71 in ?? () from /lib/i386-linux-gnu/libc.so.6
other are related to an unknown module (probably directly to the A3server always at the same adress) :
Program terminated with signal 11, Segmentation fault.
#0 0x0945a250 in ?? ()
Program terminated with signal 11, Segmentation fault.
