<p class="MsoNormal"><span style="color:#1F497D">Alright, I managed to fix this last night. This is a good lesson in due diligence. I normally use a modified android-toolchain file derived from the one available in the OpenCV source. While working this
issue I noticed that OpenSceneGraph a version of this file that share a common ancestor. My modified version of the file configures CMake to use gcc4.8 out of the android NDK while the default behavior is to pick gcc4.9 from the most recent copies of the
Android NDK.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">At some point in my development I ended up with a hybrid CMake configuration which built OSG against gcc4.9 but linked against libraries linked against gcc4.8. I was in the wrong mindset chasing this down
so I started playing with dynamic vs static configurations of the STL and the behavior when combined with the incompatible versions of libc and libc++ were very interesting. I corrected this issue last night rebuild the entire backend using a unified toolchain
and as you can guess everything is working.<o:p></o:p></span></p>

<p class="MsoNormal">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. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have an idea on common pitfalls which could cause this type of behavior?
