@amigans

has anyone here been able to successfully play level 9 in equilibrio? we can do levels 1-8 just fine, but starting level 9 gets the same crash every time.

The crash is in strcmp() but most likely the actual bug is in the application or it could be a stack overflow (you left out that part from the crashlog).
