(In reply to Greg Lewis from comment #3)
I am not proposing to interpret any SIGSEGV as a stack overflow.  I propose to
consider a SIGSEGV as the stack overflow if it occured in the range of
[guard_start; stack_end) for the given stack, instead of the current
implementation which considers the range [guard_start; guard_end) (at least
this is how I understand what is going on by your explanation).

I can also add e.g. procctl(PROC_STACKGUARD) but to convince me to do that you
would need to explain why the above approach is not sufficient.
