Building HPX leads to a segfault when it was built with gcc 4.7. This needs closer investigation
as there have been multiple reports about this segfault on IRC

It's a visibility issue, I believe:

  • The data members of a OSHL (static variable) are clearly not initialized properly, leading me to believe that there are multiple copies being accessed due to visibility issues.
  • The problem doesn't show up in debug mode when -fvisibility=hidden is turned off.

Can I ask someone else to please take lead on debugging this?

Have you tried removing -fvisibility=hidden in release mode? That should verify your 'believe' in no time.

Yes, and then the problem goes away

In this case we should remove this option for gcc 4.7 alltogether - apparently its broken.
