> When does this abort happen? When you stop it?
Output of "time lcd4linux -F -vvv" is
real 0m3.187s
user 0m0.110s
sys 0m0.075s
> Are you shure that serdisplib uses the same wiring than lcd4linux?
Yes, double (and triple) checked that.
> Are you familiar with gdb?
Nope, but I _will_ soon be familiar with it, if that's the only
way to go.
;)
BTW: The Layouts L8x2, L16x2 and L20x2 all work okay - actually
the output is still corrupted, but lcd4linux doesn't abort and
I see something which looks like heavily distorted moving bars.
It's interesting that these layouts also show the glibc free()
error message - after I kill lcd4linux with CTRL+C.
Furthermore I found out in which cases lcd4linux aborts; it only
happens when the content of the selected layout is bigger than
the lcd size (21x8 char).
Two logs attached: First one shows lcd4linux "crashing" with the
"Default" Layout, second one shows lcd4linux _not_ "crashing"
with modified "Default" Layout (DiskBar and Eth0Bar length
reduced to 11).
