Huh, looks like backtrace() is actually calling malloc().
I'd love to say I'm surprised by the tone in the comments of that bug,
but I've read enough glibc bugs to know that it was a common problem in
See however the far more reasonable and clueful:
Basically - backtrace() not safe to call from signal handlers by the
looks of it? Glumness.
Still not clear why the process is SEGVing - vp->length is 3,
talloc_array should not fail. I guess memory corruption of some sort?
