Hi,
I'm currently looking at a problem with osgExit...
I use a pbuffer and a passive window to do the rendering,
I have a class that has created an fbo object, it called
addRefCP on that ptr and in the destructor I call subRefCP.
The osgExit crashes when calling the subRefCP. I made
sure that the ref counter is >0 (in my case == 1) and
that the pointer is != NullFC. The stack trace is here:
ntdll.dll!7c91104b()
> OSGBaseD.dll!osg::WinThreadLockBase::aquire() Riga 379 + 0xf byte
> C++
OSGBaseD.dll!osg::Lock::aquire() Riga 452 C++
OSGBaseD.dll!osg::LockPool::aquire(void * keyP=0x031fc830) Riga 537
C++
OSGSystemD.dll!osg::FieldContainerPtrBase::subRef() Riga 127 +
0x15 byte C++
OSGSystemD.dll!osg::subRefCP(const osg::FieldContainerPtrBase &
objectP={...}) Riga 88 C++
The line of code where it crashes is this one:
EnterCriticalSection(&_pCriticalSection);
pCriticalSection is
- _pCriticalSection {DebugInfo=0xfeeefeee
LockCount=-17891601
RecursionCount=-17891602 ...} _RTL_CRITICAL_SECTION
- DebugInfo 0xfeeefeee {Type=??? CreatorBackTraceIndex=???
CriticalSection=??? ...} _RTL_CRITICAL_SECTION_DEBUG *

RecursionCount -17891602 long
OwningThread 0xfeeefeee void *
LockSemaphore 0xfeeefeee void *
SpinCount 4277075694 unsigned long
where OwningThread seems quite suspicious...
If I remove the addRefCP and subRefCP calls, the osgExit works
ok. osgInit, the rendering etc and osgExit run all in the same
thread! The context and the PassiveWindow is deleted _before_
calling osgExit(). Any ideas?
Regards,
Toni
