Description:
When a query is launched, it just crashes.
No warning, no error, no log.

It suddenly stopped working this week

How to repeat:
connect to a database, type a query, run it, crash

I also get this issue on Windows 8.1 - but only when connected to MySQL 5.7 databases, not 5.6, 5.5 or 5.1

Thank you for the details.
This reminds me of Bug #81972, but cannot confirm since no back trace etc
I would suggest you to launch WB with --log-level=debug3 option and see if this helps. See https://dev.mysql.com/doc/workbench/en/workbench-reporting-bugs.html

See my attached crash log above ^^^

Trimmed crash report from OS X, main culprit "pointer being freed was not allocated".

Its intermittent, I can start the app run the query, works, wait awhile connect to another DB run a query, crash. Restart run a query, crash, restart run the same query, works. Besides a missing null check, its like a timer/thread event isn't done allocating before a dealloc happens.
