* absl: add a stack unwinding testAbseil Team2023-01-201-0/+47
END_PUBLIC absl: relax frame size check in x86 stack unwinding Currently the unwinder stops whenever it sees a frame >100000 bytes. There may be such legitimate frames, the default stack size is O(megabytes). Only do this check if we are not within the thread stack bounds. The thread stack is assumed to be readable, so the worst thing that can happen if the large stack frame is actually bogus is that we will add one/few wrong frames and stop.
