Hello Matt,

Without the corefile, we know nothing, sadly. The binaries are PIE and we need to know not only
where they were mapped but also where glibc was mapped, how the stack(s) looked like and much more
context.
OTOH, it looks like the corefile may be enough very soon, if our planned magic actually works. I’ll
know hopefully at the end of this week.
Sadly, I don't have a corefile handy, but that shouldn't stop you! If you have symbols handy, both
of the first two segfaults show a crash at instruction 278313 within the bird binary -
(0x000056552fb27f29 minus the base address of the binary at 0x56552fae4000 and 0x000055a6f3935f29
minus the base address of the binary at 0x55a6f38f2000). That should suffice to turn up the line of
code where the segfault happened, which presumably tells quite a lot, even if not as much as a corefile.
The BFD restart shows a crash at instruction with offset 277887.
