Thanks!
So far I managed to reproduce all the issues except for crashing. 
(without Raspbian or Pi)  We'll keep looking into those.

The crashes themselves might be related.  Raspbian [faq] discourages
such mixing.  The "WILL NOT RUN" probably doesn't apply here (I think
it's just about v7 instruction support), but there are also parts like
"libraries build slightly differently".  Still, I understand too little
about the compatibility, so it's well possible that none of your issues
is related this mixing of binaries.
