Hi,
I'm building OpenSceneGraph from the head of the trunk on Mac OS 10.7 Lion
using CMake. The build works straight out of the box defaulting to the llvm
compilers.
I'm using OpenSceneGraph in a project built using gcc-mp-4.7, and so linking to
the libraries built in the above step from my project.
I'm experiencing a problem with primitive sets at runtime - Namely, a primitive
set I create causes a crash when it goes out of scope.
I've managed to boil my problem down to a very simple implementation:
Code:
int main(int argc, char *argv[])
{
osg::ref_ptr<osg::PrimitiveSet> p = new osg::DrawElementsUByte();
return 0;
}
When executed, with the OSG libraries built using llvm, and the program built
using gcc-mp-4.7, the following happens:
Code:
Tobys-MacBook-Pro:xxx tobiasduckworth$ ./3DRecon.app/Contents/MacOS/3DRecon
3DRecon(23649,0x7fff7612f960) malloc: *** error for object 0x10e163ec0: pointer
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
However, if I build the program using the same compiler (llvm) as OSG, then it
runs fine.
My program uses OpenMP, so I need to use gcc to get this to compile, otherwise
I could move to llvm.
I also tried to build OSG using gcc, but this failed due to osgViewer using
Objective C.
Does anyone have any idea what might be going wrong here?
Should I be able to build OSG using llvm and my application using gcc?
Hoping someone can shed some light,
...
Thank you!
Cheers,
Tobias
