I'm currently debugging a random segfault in libunwind. Where have I gone wrong in my life?

Now i turned it into an anti-Heisenbug! I minimized the crash into something that happens only when I run it in gdb, and not when run standalone. Better than the reverse, I suppose?!

it's simply the fact that gdb turns address space randomization off by default. if I run it with setarch -R, the reproducer also crashes reliably.
