Comment:

 This certainly sounds like a bug in the compacting GC.  Without means to
 reproduce it though, it's impossible to diagnose.

 If you could reproduce the error in non-proprietary code, or somehow
 arrange to give me the code with a no-redistribution license, that would
 help a lot.

 If you need to use `-M` without the compacting GC, the workaround is to
 add `-c100`, which should disable the automatic compacting GC threshold.
