Replying to richardpl:
I see no crashes just some strange uninitialized issues under valgrind.
Hi richard, yeah this may be. I just was not sure if there is a bug or not and thought its good if some professional checks it. Thought maybe it could be helpful.
Should i change the ticket description?

None of the text files you attached show a crash and I cannot reproduce any irregularity with any of the files you attached.
I see no crashes just some strange uninitialized issues under valgrind.
