This happens randomly on our build server, but it's also been known to happen locally. Full error message below.

Still happens quite frequently when loading code using Iceberg in the latest Pharo 8 image on a CI server

I got this error two times today. Once in 32 bits and once in 64bits.

I still get this error sometimes. On Windows and on Linux. I get it often on travis-ci which causes my builds to fail (then I restart the build and it passes), but it happens on my PC with Windows too. PharoDebug.log
