Bug 108564 – gtkwave segfaults on analog wave display

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Dan McDonald 2005-10-08 21:46:55 UTC]

gtkwave does a segmentation fault when I try to look at a signal as analog
(Edit->Display Format->Analog). 

Reproducible: Always
Steps to Reproduce:
1. Open a VCD in gtkwave (I've only tried VCD's generated by vvp/iverlog)
2. Menu: Trace->Show All Traces
3. Select a signal on the left pane (single click until it changes bg color)
4. Menu: Edit->Display Format->Analog

Actual Results:  
Segmentation Fault

Expected Results:  
Display a pretty analog graph.

I emerged it with FEATURES="nostrip" and checked the stack. See the attachment.

I'll attach a really basic VCD to test with.
I'll also do a check out from cvs to see if it still segfaults. Development
seems to have stagnated on this project, however.

I can't seem to find any CVS. The last update to the program was more than a
year ago, which was a year since the update before it.

This needs to go upstream (not sure if upstream will do anything, though) as
it's a bug in the actual application rather than Gentoo packaging. If you are
able to produce a patch of some sort then please reopen this bug and I would be
very happy to include it. Thanks!
