I have absolutely no ide why this would happen. From the error message, you're 
using 1.4.0 or 1.4.1, so you might want to try to update to 2.0.x, maybe that 
fixes anything.

Aside from that, the code you sent does not look wrong, so I suspect either a 
bug in your port or something overwriting some memory...
