Constant Random Crashing
kip:
Hey guys,
I am using the latest svn revision 2914 and I am still getting regular random crashes. When I run from console, I catch its output before aborting...
codeblocks: /build/buildd/libcairo-1.2.2/src/cairo-ft-font.c:681: _cairo_ft_unscaled_font_set_scale: Assertion `error == 0' failed.
Aborted
I was using the latest version of libcairo2 (1.2.2) out of Ubuntu's Edgy and still to no avail.
It is very difficult to get any work done with gedit. Any help would be appreciated.

A
It wasn't wide enough and I tried to resize it. C::B crashed.
This is the output from C::B:
Steps to reproduce
1. Open C::B
2. Go to File-> New -> Project
3. Choose Console Application
4. Complete the Wizard
5. In the Management window, double click on Sources->main.cpp
6. Click once in the editor window
7. Grab the separator that splits the editor from the symbols browser. Drag 5 cm left. Sometimes it crashes after the first drag and drop. If it didnt crash, drag the separator left one more time. It will crash with the above error message printed in the console.
If there is no project opened, moving the separator did not crash Code Blocks. Most of the times, you dont even have to open main.cpp and click in the window. Just create a new Console project and try to resize the Symbols browser. I always get the same error.
I even got this error when double-clicking on main.cpp, but I couldn't reproduce it.
On a different occasion, while editing the text and then resizing the Symbold Browser, I got this error:
--- Code: ---(codeblocks:4439): GLib-CRITICAL **: g_queue_push_head_link: assertion `link->next == NULL' failed
codeblocks: cairo-ft-font.c:678: _cairo_ft_unscaled_font_set_scale: Assertion `error == 0' failed.
Aborted
--- End code ---
However, I couldn't reproduce this either.

It is annoying the hell out of me. What is really scary is that so many people have pointed this out on the forum and the usual response is that it is a problem with libcairo and that it was fixed an eon ago. Everyone is using whatever version of libcairo is most readily available to them through their package manager (I am on Linux). Only Edgy repository for Ubuntu has the latest libcairo and even that one did nothing any different.

No one said that. As a matter of fact, I don't have any of these problems in either Ubuntu 5.10 (32bit) or Ubuntu 6.06 (64bit). And no, I haven't touched libcairo: whatever comes with the distro.
Some people report having this problem, others don't have it at all. Although it's not a C::B problem per-se, we 'd love to fix it but it's darn hard to even try since we can't reproduce it. At least no one in the team can, to my knowledge...
