I ran into this and had to pkill julia:

I might need some help debugging this. I can't replicate this on mac or windows, and I haven't been able to access a linux machine with a GUI terminal (and attempts to set up VNC on a few machines that I do have access to haven't yet suceeded 😞 ) . Might help to create an rr trace?

[mbaz]

I'm having trouble getting a trace. It seems that Julia crashes so bad that the trace is not created before Julia terminates. I'm getting this stacktrace. Notes:

• I exit the plasma window by hitting ESC after a few seconds.
• I got the malloc() error immediately after hitting macro m()<enter>.
• Then Julia was stuck after the signal (6). The stacktrace appeared after I hit Ctrl-C.

Any suggestion on how to get a trace under these conditions? I'll be happy to run any tests you need.
