[issue23654] infinite loop in faulthandler._stack_overflow

[Matt Frank]

Matt Frank added the comment:

This is a patch that turns off the Intel Compiler's optimization for the stack_overflow() function.  It turns out that icc doesn't support gcc's __attribute__((optimize("no-optimize-sibling-calls"))).  Instead I used an ifdef'd intel-specific pragma that turns off optimization completely for just this function, and just for the intel compiler.

This particular pragma has the benefit that it should also work with the Intel compiler on Windows without needing further ifdefs.
