Hi there.

17B7 has been working well all day --- then this memory allocation crash:

Sorry, but this post is not helpful for the developers. You are aware that you are using beta software?
So, please support them: viewtopic.php?f=21&t=90190

Here's the Resolve Log:

Of interest the crash is not recorded in the archive. There is some debug information - but not from the crash.

In this case - the screen just went black and the iMac restarts.

Regards


Andy
