Hi all,
I have a test app that seems to crash in random locations. After
probing with gdb for a bit, it appears that an interupt occurs at some
point and then the app crashes with:
ASSERT FAIL: <3240>sched.cxx[160]static void
Cyg_Scheduler::unlock_inner() Bad current thread
I am thinking that this is probably a corrupt stack problem, but I am
not sure how to know for sure. Assuming it is a stack problem and it
is just too small, can someone explain how I can set/check the stack
size of main()?
Thanks,
--
Mike

Set this variable:
cdl_option CYGNUM_LIBC_MAIN_DEFAULT_STACK_SIZE {
user_value 65536
};

Thank you. The app now runs fine. I guess that is confirmation that it
was a stack problem :)
