BitBltSimulator assertion failure

Hi Eliot, If I try to run Pharo with the latest VMMaker (eem.2460) it results in the following error in BitBltSimulator. Does this look familiar? Thanks, Alistair 17 October 2018 9:21:26.389168 am VM: unix - Smalltalk Image: Squeak5.2rc1 [latest update: #18220] - The image was built about 5 days ago and VMMaker updated via Monticello.

Yes. I am working on fixing a bug in BitBlt where the copyBits primitive accesses a word past the end of the source bitmap.

I don't think I would have come up with this work-around. Interestingly the image runs successfully with the CogVMSimulator, but just ends up in the idle loop when using StackInterpreterSimulator. Anyway, I want to focus on finishing off FileAttributesPlugin first. Thanks again, Alistair |
