The first backtrace, frame 13 has delete 0. Since delete 0 is always valid (and 
should just be a NOOP) that shouldn't crash. But in the next frame the pointer 
dereferenced is 0x6 so there is something strange going on:

#12 0xb60d1049 in __libc_free (mem=0x6) at malloc.c:3699
#13 0xb6279f4f in operator delete (ptr=0x0) at
../../../../libstdc++-v3/libsupc++/del_op.cc:44

I just wonder why this is libstdc++-v3, openSuSE 11.2 uses gcc 4.4 by default?
