I was having a double free issue too. Deuce commited a fix just about 2
days ago.

http://cvs.synchro.net/cgi-bin/viewcvs.cgi/src/uifc/uifc32.c?view=log

Maybe do another update and recompile. I noticed that I had to force scfg
and echocfg to recompile for some reason. You might want to use cleanall.sh
first. Check the data of the binary in your exe directory to confirm whether
it rebuilt.
