#8508: Created thread segfaults when memory is scarce
------------------------------+---------------------------------------------
 Reporter:  anonymous         |       Owner:  anthonyw
     Type:  Bugs              |      Status:  new     
Milestone:  To Be Determined  |   Component:  thread  
  Version:  Boost 1.53.0      |    Severity:  Problem 
 Keywords:                    |  
------------------------------+---------------------------------------------
 The following code will segfault in the created thread if memory is
 scarce:

 {{{
 #include <boost/thread/thread.hpp>

 void thread_main()
 {
 }

 int main(void)
 {
         boost::thread t(thread_main);
         t.join();
 }
 }}}

 This was run in GDB with ulimit -v 150000 applied beforehand. You'll have
 to experiment with the exact value.

 GDB output:
 {{{
