Well the meaning of exceptions is dependent on the platform you are 
using, so we can not answer without more information.

However, you can ask to receive a signal at the point where the 
exception happens, doing as in ksrc/skins/native/snippets/sigxcpu.c, 
only using pthread_set_mode_np instead of rt_task_set_mode, if you use 
the posix skin.

Alternatively, you have a way of knowing directly where the exception 
happens by disassembling your example program and look where 0x10017cec is.

P.S: if you do not like the way your message looks when I rewrap it, 
send it correctly wrapped.
