</h2></div></div></div><p> The parallel mode STL algorithms are currently not exception-safe,
3 i.e. user-defined functors must not throw exceptions.
4 Also, the order of execution is not guaranteed for some functions, of course.
5 Therefore, user-defined functors should not have any concurrent side effects.
6 </p><p> Since the current GCC OpenMP implementation does not support
7 OpenMP parallel regions in concurrent threads,
8 it is not possible to call parallel STL algorithm in
9 concurrent threads, either.
10 It might work with other compilers, though.
