Hi,
My osgEarth based application was crashing from time to time (3-4 times a day).
It was not easy to debug. But eventually I've caught the problem place in
Release with Debug info mode.
DatabasePager thread crashed in osgText/Font.cpp file in the function:
Code:
osg::ref_ptr<Font>& Font::getDefaultFont()
{
static OpenThreads::Mutex s_DefaultFontMutex;
OpenThreads::ScopedLock<OpenThreads::Mutex> lock(s_DefaultFontMutex);
static osg::ref_ptr<Font> s_defaultFont = new DefaultFont;
return s_defaultFont;
}
I suppose that scoped static variable initialization is not thread-safe.
Perhaps the s_DefaultFontMutex variable should be the global.
Regards,
Alexander
