A:
I think the C++ standard doesn't say anything about thread-safety. Threads are simply not (yet) part of the concept. But I'm sure each compiler vendor has his/her own answer to that question. Check your compiler's documentation. I'd be surprized if the built-in new/delete operators were not thread-safe.

I was a bit irritated, pthreads is a C lib and I thought the question was regarding some new/delete implementation in pthreads!!! The default new/delete are thread safe (global heap lock is used, which costs some performance drop in single threaded apps)

A:
As far as I know, all system functions are thread safe, if you build your project with 'Multi-threaded' run-time libraries.
