#8788: SIGSEGV on thread::join
 Reporter: anonymous | Owner: anthonyw
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: thread
  Version: Boost 1.53.0 | Severity: Problem
 Keywords: SIGSEGV, thread |
 Fedora 19, x86_64.

 The following program:
 #include <boost/thread/thread.hpp>

 void myFunc()

 int main(int, char **)
   boost::thread p(myFunc);


 When compiled with:
 {{{g++ -o bthread bthread.cxx -lboost_thread -D_GLIBCXX_DEBUG}}}

 Results in the following segfault (with -ggdb added):
