I have tried running the current SVN version (before today there was a regression bug causing core dumps in the SVN version) and I do get a core dump if I do not specify the processor otherwise it seems to run with a hex file.

Attaching a sample hex file along with the exact command used would be helpful.

You submitted several bug reports which is fantastic, but it would be better if you would log into SourceForge before creating reports. This allows you to better track your reports. If you do not have one, create a SourceForge account.
