[osg-users] Android - corrupt block passed to dlfree

I've been chasing a problem for the last few days regarding OSG and Android. Today I finally decided to work forward from the osgAndroidExcmpleGLES2 from the osg example source. The issue manifested very quickly in the application startup so I am fairly sure I've built my Android ARM OSG libraries incorrectly.
The symptom seems to be a block of uninitialized memory being passed to a dlfree call . The back trace can start from numerous sources based on the example code, but the failure is always based in std::allocator<char> >::~basic_string(). I would normally blame STL incompatibilities, but with the osgAndroidExampleGLES2 I can confirm that both the APK and the OSG libs were compiled against gnustl_static so I wouldn't expect this to be the core conflict.
Does anyone have an idea on common pitfalls which could cause this type of behavior?
