[osg-users] Crash in ReaderWriterCURL::readFile when used with DatabasePager

[Hartwig Wiesmann]

Hi Robert,

I did some further investigations: I added in ReaderWriterCURL::readFile an atomic counter and stopped in the debugger whenever the atomic counter reaches 2 (means 2 threads are running at the same time an instance of ReaderWriterCURL::readFile).

The debugger showed clearly that there are two threads running but OpenThreads::Thread::CurrentThread() always returned the same pointer to Thread. Therefore, getEasyCurl() does not work correctly.

PS: I do not know if OpenThreads is broken on macOS?! I compiled OpenThreads with


Code:
#define _OPENTHREADS_ATOMIC_USE_MUTEX 1




but this should actually not matter.

Cheers,
Hartwig
