does your system allow gdb to attach to processes? some disable that by
default, which might lead to weird behaviour.
oh, also i'm quite sure we don't restrict ourselves to async-signal-safe
functions in the sigseg handler (man 7 signal). so i guess every once in a
million this is quite prone to deadlocking itself. i doubt that's the
reason for you though if you get it every time.
