Does your default configuration file contain HMEEnable = 1? If so, that enables the HME scheme and does not see that you are not using SearchMode = 3 (EPZS) and the code crashes. We did not yet add "protection checks" in the code to test all the allowed modes for the HME (in general the scheme only works for EPZS and should not be used with any other scheme) because of lack of time, but if you try to run the encoder with "./lencod.exe -d encoder_main.cfg" you should likely see that this is working properly. We will add those checks later (not high priority unfortunately).

I guess, we should add these sanity checks with the next release. I'm creating development branches.
