[osg-users] OpenThreads trunk latest mods crashes on mingw32 g++ Windows in Release

[Trajce Nikolov NICK]

Hi Robert,

when I browse the code I seeing this in the Atomic.h/cpp

Revision 13132 <http://trac.openscenegraph.org/projects/osg/changeset/13132>
, 8.1 kB (checked in by robert, 3 days
<http://trac.openscenegraph.org/projects/osg/timeline?from=2015-04-30T16%3A04%3A51Z%2B0200&precision=second>
 ago)

enabled

And I reverted back the changes to match 3.3.7 but it still crashes in
Atomic::operator--()

Debug works just fine, so I have no idea what is wrong
