#10058: Null pointer access in once
------------------------------+----------------------
 Reporter:  michael.kaes@…    |      Owner:  anthonyw
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  thread
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------
 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.
