Mac VM crash logs

When a unix vm crashes, it dumps a crash log to stderr or
stdout.

When a windows vm crashes, it appends a crash log to
vmpath/crash.dmp

Where does the mac vm hide such niceties?

Newer OS X versions store debug output in a database rather than text files.

Apple provides the "Console" app to browse it, including crash reports.

Run it, select "all messages", and type "squeak" (or whatever the name of your VM is) in the filter box to see only messages pertaining to Squeak. This is where stderr goes to, so you see e.g. the printStacks output there.

In the same app, click "User Diagnostic Reports" to see stored crash reports. The context menu will let you reveal them in Finder.

Oh, and the command line equivalent would be

syslog -C | grep -i squeak

It is somewhere in your home dir ~/Library ..

~/Library/Logs/DiagnosticReports is where 10.5 and later store it

~/Library/Logs/CrashReporter is IIRC where 10.4 and previous stores it

e.g.

Library/Logs/DiagnosticReports/Teleplace_2011-03-11-121210_McStalker.crash

The Mac vm uses the same code as the unix vm to trap the signal
, then to dump the squeak stack. If the squeak oops space is corrupt
you can have that code fail too. Otherwise You should see lot's of
messages in the syslog
