pure virtual called is usually a problem of code vs compiler vs linker.
(child class declared the method, but did not implement it)
It can also be a problem of a fool pointer being interpreted as a
pointer to a class that is not the expected one anymore. (such as to a
deleted instance) and then, it can depend a lot on the actual system
usage about what is found in the memory for that pointer. Memory
problems can be due to race or serialization between cores.
I tried it on 64 bits ubuntu 12.04, with g++ 4.6.3, and 4 cores.
It could also be tied to the subversion of g++ (I cannot update that
system, and maybe 12.04 did not stay at 4.6.3), or 32 vs 64.
