Hi,
could you try to revert main.c to version 1159. I moved the display of
the programmer before the open command, to see their pin outputs before
they try to open, so I could see what they had read from the config file
and internally processed with the new pin definitions. (I did this
testing without having actually the hardware connected, so open always
ended the program. And originally I did not intend to check in the file.)
It seems jtagmkii_display needs you to call jtagmkii_open beforehand. At
least I get there some problems (with Ubuntu 12.10), and it looks as
would be overwritten somewhere some memory. This might be the reason for
the problem. reverting the file should make disappear the segfault. On
the other hand, if this really overwrites some memory then there must be
some other problem in the code of jtagmkii too, as normally some
checking of return values or error codes should reveal the fact that the
progammer was not opened beforehand.

OK, tried it on an Ubuntu, and can confirm the segfault:

So "port" is given as 0x01 here. Stack frame #1 is:
pgm->vfy_led(pgm, ON);
No idea offhand why that triggers a jtagmkII_open() with bogus
arguments.
