It's not theoretical since there were multiple users reporting unwinding issues,
so clearly doing CFLAGS="-

As described in PR71951, if libgcc is built with -fomit-frame-pointer,
unwinding crashes, for example while doing a backtrace. The underlying
reason is the Dwarf unwinder does not setup the frame pointer register
in the initialization code. When later unwinding a function that uses
the frame poin
