Please provide a dump that is from your segmentation violation, and which was made with the debug symbols available.
If this really was an abort and not a segmentation violation, it occurred when trying to allocate memory in app_konference, and there will be an assertion failure message, but you haven’t captured it directly, and, because you have no debug symbols, you haven’t captured it as a parameter of a function call.
Assertion failures in malloc are normally caused by memory corruption, and that corruption may have been associated with another thread and happened somewhat earlier.
