You are correct, I am following the procedure as you show above and it
definely and reliably segfaults the first time it tries to change the
state of the LCD's E input.
Also, I am using the latest release versions of gputils, gpsim and the
lcd as provided on the official sites. Also, I have installed and tested
them as laid out in the repective INSTALL and README files.
I'm not ruling out that the problem source could be something silly on
my part, I just don't know where to look anymore.
I am interested in getting this working so would you suggest I tackle
the CVS version?
