I get this error a lot. Is this a known error?

[David]

This is not a known error. Does it happen every time you run BC? It appears that it is happening as soon as you call BC - is that correct?

David

[rfkortekasa]

No, it doesn't happen every time, but most of the times I'm running it.

I must say that most of the time it happens when running it with git difftool.
But also without. And it wouldn't even start but crash directly after starting.

[Aaron]

Hello,

Thanks for the info. Are you running the 32bit or 64bit version of OpenSuse 12.3? Which installer did you use to setup BC3?

[rfkortekasa]

I'm using the 64-Bit version of OpenSUSE and used the RPM package from:
http://www.scootersoftware.com/beta.php?zz=beta4_dl

[Aaron]

I'm configuring this VM now.

Our current hunch is this may have to do with having either your settings directory or program directory in a write protected area. It's certainly possible this is something our beta installer had issue with; is there anything non-standard about your current OpenSUSE configuration or where the RPM installed the application?

When you are calling from the command line, you are using "bcompare", correct? Are you passing any other parameters commonly when you see it crash?

[rfkortekasa]

No, there is nothing special on my OpenSUSE. I Just use the OpenSuse from the installer with Gnome. When running it I mostly supply 2 files or folders to compare. And I'm using it a lot with git difftool.

What I noticed today is that when I started it with two files it crashed a lot of times, but when just starting it with bcompare and selecting the last session from the GUI it worked fine.

The runtime error that it returns is always the same, except that the amount is different. Most of the time it shows the error 3 times. But i have seen also 2 or 1 times showing the error.

Removed stix-fonts and now BCompare starts normaly.

[David]

Is the above a dump from strace? If not where?

Thanks

[rfkortekasa]

My problem is different. I don't have the stix font installed and the trace with gdb always ends on QPixmap_isNull.

[David]

Good. Stack trace that ends at QPixmap_isNull makes my first response wrong i.e. it is a known error that we have fixed in the repository. If you would like to get the most recent nightly build to check if the error is fixed please send an email to [email protected] with a link to this forum thread and our tech support folk will tell you how to get a nightly build.

[minde]

Yes, from strace. I just recompiled freetype (enabled debug +debug symbols) and then fc-cache exits with an error 'assertion failed on line 383 of file freetype-2.5.0.1/work/freetype-2.5.0.1/src/cff/cf2ft.c'.

[rfkortekasa]

HI David,

Thanks for the information. I've sent the request to the support desk.

Best regards,
Ronald

[Zaister]

I've been getting the same segmentation fault error for a few days now too, both with BC 3.3.8.16340 and 4.0.0.17451. I suspect it might be due to a recent update in glibc from 2.17 to 2.18, is that possible?

I also have freetype-2.5.0.1, but I do not have the stix-fonts package installed. What can I do?
