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().
