10058	Null pointer access in once	michael.kaes@…	viboes	"There is the possibility that the call to malloc in 
{{{
thread_detail::uintmax_atomic_t& get_once_per_thread_epoch()
}}}
in the file once.cpp returns null.

This would lead to undefined behavior as this pointer is later on dereferenced.

Attached is a patch that adds a check for the null pointer and throws an exception in this case."	Bugs	closed	Boost 1.56.0	thread	Boost 1.55.0	Problem	fixed
