[bug-gv] X11 bug in gv-3.6.3

[Karsten Trulsen]

I think there is a bug in gv-3.6.3 regarding the way it handles X11.

I (successfully, without error messages) built and installed gv-3.6.3 on 
a machine:
Linux 2.6.18-8.1.8.el5 #1 SMP Mon Jun 25 17:06:19 EDT 2007 i686 athlon 
i386 GNU/Linux

Then I ran the program without arguments:
gv
This produced the output:
Warning: Representation size 2 must match superclass's to override 
internalWidth
Segmentation fault

Then I ran the program using valgrind:
valgrind gv
This produced an endless stream of errors, starting with the following:
