Hi Jean-Sébastien I got the same problem using VS8, my app crash at exit in osgdb_freetped.dll.
It crashes at line : if (getDeleteHandler()) deleteUsingDeleteHandler(); in osg28-osgd.dll I'm using latest freetype lib 2.3.5 2008/1/7, Jean-Sébastien Guay <[EMAIL PROTECTED]>: > > Hello all, > > Is anyone else seeing a crash on exit with OSG applications (even > osgviewer and the examples) under MS VS8.0 when running in the debugger? > > To be specific: > > * Running in Visual Studio 8.0SP1 > * Debug configuration > * Mike's 3rd Party binaries for VS 8.0SP1 > > Repro steps: run osgviewer with cow.osg as argument (in debug properties). > > A) If you just do some things and exit, no crash on exit. > B) If you press 's' (or I guess any other text - anything that will > load osgdb_freetyped.dll to be loaded), and then exit, crash. > > Running from the command line does not show any problem.
