while running a debug squeak.cog.spur macos x64, I noticed repeated logs in
> (((usqInt)sourceIndex)) < endOfSource 2132
This corresponds to failing assert: in BitBltSimulation slang
self assert: idx asUnsignedInteger < endOfSource.
^self long32At: idx
Maybe it's a well known bug, but it's easy to trigger if you are after it:
Open Squeak5.1-16548-64bit.image (I took that of nsboot while testing
failing Newspeak bootstrap
Open TestRunner and run all tests...
