The parallel mode STL algorithms are currently not exception-safe, i.e. user-defined functors must not throw exceptions. Also, the order of execution is not guaranteed for some functions, of course. Therefore, user-defined functors should not have any concurrent side effects.

Since the current GCC OpenMP implementation does not support OpenMP parallel regions in concurrent threads, it is not possible to call parallel STL algorithm in concurrent threads, either. It might work with other compilers, though.
