Hello, this issue is fixed by r25595.
It seems to be a compiler bug in GCC v4.2.? ... When using assert() within OpenMP-parallel regions the compiler prepends an extra '_' to the symbol __buildin_expect(), so the linker reports undefined references. The solution is actually a workaround where an own implementation of assert() is used to prevent references to __builtin_expect().
