Description

We are parsing the same xml in multiple threads, which contains a schema. Very frequently, at least once for every tinderbox build, we get the following core dump:

I looked into it and found that the initialize of GeneralAttributeCheck::mapElements seems to fail. Although the mutex (sGeneralAttCheckMutex) contains a valid mutex, every single member field that should get a value (setUpValidators,mapAttributes) is null.

I was net yet able to find out how this is possible.
