[GTK HID] DRC window causes pcb to crash

[Bert Timmerman]

Hi all,

[GTK HID] DRC window causes pcb to crash.

Steps to reproduce:

1: Open a layout (for example "example/LED2.pcb")

2: Open the "DRC window" from the "Info" pull down menu.

3: Click the "Refresh" button in the DRC dialog window.

4: Pcb crashes with the CLI message:

<quote>
failed to create pixmap

Gdk-ERROR **: The program 'pcb' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 12180 error_code 9 request_code 55 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
aborting...
Aborted (core dumped)

The "Design Rule Checker" was NOT run from the "Connects" pull down menu prior to opening the DRC dialog window.

Another series of steps to reproduce:

1: Open a layout (for example "example/LED2.pcb")

2: Start the "Design Rule Checker" from the "Connects" pull down menu.

3: Pcb crashes with the same CLI message.

Kind regards, Bert Timmerman.

I can't reproduce this error. I have tried it with git head and 20101129 on Ubuntu 11.10 .
Can you please give some more details:
- Which pcb version
- Which distribution
Kind regards,
Felix

[Bert Timmerman (bert-timmerman)]

Hi,

It took me some time to get back to this bug (too busy day job ...).

The pcb version is git HEAD as of April 18th 2012.

The distribution is Fedora 13 (no pending updates).

Here follows a backtrace:

I can confirm this bug using latest build of PCB from git (pulled just now, rebuilt and checked)

System info, using Nvidia graphics card, dual head 2x HD screens, Ubuntu Studio desktop environment.

#: uname -a
Linux ed-desktop 2.6.38-14-generic-pae #58-Ubuntu SMP Tue Mar 27 19:06:30 UTC 2012 i686 i686 i386 GNU/Linux

#: lsb_release -r
Release: 11.04

Running the DRC check seems to cause the crash, as others stated displaying empty DRC check window looks to be ok.

[Traumflug (mah-jump-ing)]

I can't reproduce this with current Git HEAD. No messages to the command line, much less a crash. There was some work on the DRC mechanism recently, so it's very likely a crash would have been noticed.

In case the problem persists, please open a new bug. Regardless, thanks for reporting!

[Chad Parker (parker-charles)]

Already marked complete in gEDA project, marking complete in "pcb".

[Bert Timmerman (bert-timmerman)]

Hi Chad,

I just reproduced on my Fedora-13 box.

It's still not working for me (never use DRC, because of this).

Kind regards,

Bert Timmerman.
