I am sorry, I was a bit tired yesterday, was late in the night here.
I have posted the core dump on github
https://github.com/cruwe/debug-blobs
I hope that is more helpful than the gdb output from this morning.

Punctuation matters:
"Lets eat Grandma." or "Lets eat, Grandma." - Punctuation saves lives.
"A panda eats shoots and leaves." or "A panda eats, shoots, and
leaves." - Punctuation teaches proper biology.
"With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead." (RFC 1925)
