I am using boost::threads for an application that allocates space in heap with the new operator. Therefore, different threads allocate memory in parallel. Do I have to link my application to any other library apart from the libboost_thread to guarantee a thread safe memory allocation?
I searched online, but I got more confused. Do I have to define the -D_REENTRANT or the -pthread symbol?
Somebody else could probably provide a much better and much completer
answer, but here's what I think I know. Perhaps you already found the
answer in the meanwhile...
Whether memory allocation is thread-safe depends on your allocator. If
you didn't explicitly specify the allocator you'll be using
std::allocator<yourType>. IIRC, that allocator is thread-safe so you
don't need to worry about additional compiler flags (as far as memory
allocation is concerned).
