Hi,
while play levels higher than about 75 in 2 player cooperative mode, I get
segfaults everyonce in a while. Here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.
0xb7dc5cf7 in memcpy () from /lib/tls/libc.so.6
(gdb) bt
#0 0xb7dc5cf7 in memcpy () from /lib/tls/libc.so.6

#4 0x0807677e in main (argc=136572936, argv=0x0) at init.c:936
(gdb)
I applied the attached patch and it fixed the problem for me.
