Mis-addressed - now even more badly formatted...  Sent from my Samsung Galaxy smartphone. -------- Original message --------From: "p.w.stephenson" Date: 24/04/2017 19:00 (GMT+00:00) To: Bart Schaefer Cc: Zsh Hackers' List Subject: Re: Call stack issues when running trap handler (Apologies for lack of format, now out of office on phone.) Tried with oldish Fedora (like about 7 or 8 years), 32 bit, and also RedHat also a few issues back but not quite so old, 64 bit. What about environment: standard variables, open file descriptors, things in path...? Can't think of anything obviously relevant. pws Sent from my Samsung Galaxy smartphone.
