I see.  Well, using __stack_chk_guard from ld.so is not a good idea.  It
won't be initialized, because that's only done if THREAD_SET_STACK_GUARD
isn't defined.  I think you really just need to configure your compiler
correctly.  See TARGET_LIBC_PROVIDES_SSP and the configure check that
sets it.


Thanks,
Roland
