Crash report? What's your build_arch?

Crash report?

Not sure how to generate a crash report, but I did try setting ulimit -c unlimited and reproducing the segfault but there was no core dump. I did figure out how to reproduce this in Instruments (which I just used for the first time), so I'll attach the resulting trace in case it's helpful. If there's anything more I can provide, please let me know how.

What's your build_arch?

are you able to reproduce in any of your testing environments?

Replying to jabronson@…:

Not sure how to generate a crash report

Should be automatically generated in ~/Library/Logs/DiagnosticReports or ~/Library/Logs/CrashReporter (or possibly in /Library rather than ~/Library, this seems to have changed recently.)
