sc_cor_qt::stack_protect

Hello all,

I've recently created a vary large model and I have encounted an assertion violation in sc_cor_qt::stack_protect.  The mprotect system call returns a -1 value, triggering the assertion. The errno is ENOMEM. There is no memory allcoated expilicitly in stack_protect so it must mean that the address passed to mprotect is invalid.

If I remove the stack_protect call from sc_thread_process::prepare_for_simulation then my model runs just fine. So it appears that stack_protect is not strictly needed, but probably a good idea to leave it in if you can.

Anyone else ever have any problems with the stack_protect call?

Thanks,

Terry
