Got the same thing here and I don't understand why there is no debugging info. 
Probably because it happens in the program, contrary to what I thought. I 
added a printf just before the main of the program compiled is run and it's 
systematically displayed but any printf in the test itself is not displayed. 
So the crash happens in the very first instructions of the compiled program. 
I'll try to dump the main into a file and maybe I will be able to see a 
problem. What puzzles me is that it's random while the code generated should 
be always the same. I thought about an alignment problem but all run are 
aligned the same way (on 4 bytes while it should be 8 bytes).

I have to leave now but I'll keep you informed. About the symlinks, I'll 
download a rasbian image and look how the FS is done.
