OpenCV crash during shutdown with Apache 2.2 worker #556

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When running load tests on latest trunk with apache 2.2 worker the following 
backtrace is generated intermittently. I have not seen it happen with prefork 
or event mpms.
