Thanks for the clarification, I misunderstood "16-byte stack alignment."
The problem seems to be in the statethreads library:
/* Make stack 64-byte aligned */
if ((unsigned long)sp & 0x3f)
sp = sp - ((unsigned long)sp & 0x3f);
After I hacked this (subtracting 8) the program doesn't crash
anymore. I'm taking this to the statethreads mailing list.
Thanks for all the information/help!
