Bug 20641 – REGRESSION: Crash in GlyphPage::fill on more complex mapping applications

• Component: SVG
• Status: RESOLVED WORKSFORME

[Andreas Neumann]

On some of my more complex SVG mapping examples I get crashes with the current nightlies.

Here are two URLs where I get the crashes:
http://www.carto.net/williams/yosemite/
http://www.geofoto.ch/geophotomap/

It is hard to isolate the problem, but maybe someone could read something from the crash-logs. I can certainly help to investigate the problem with your help.

Thanks for having a look at these two examples.

Seems we're passing bad stuff off into the font system.

I am not seeing this bug yet on windows r36012.  Maybe it happened after this nightly.  I will check when the next windows build is posted.

[Andreas Neumann]

could be that it only happens on Mac? The bug has been around for a while on my machine, but I only reported it now.

The SVG fonts might be an issue. Both examples use SVG fonts.

I cannot reproduce this with a local build of r36264 - but from the looks of the crash log, the problem may easily be Tiger-only.

I was just testing the issue on a G4 Powerbook, also Tiger. It also crashes. I will also submit the crashlog from the G4.

Any idea when the regression occurred?

[Andreas Neumann]

I don't know when it appeared.

I know that it is at least 3 weeks old - but it may be older. I was busy back then and did not do a lot of testing.

I'm not able to reproduce this.

[Alexey Proskuryakov]

I couldn't reproduce the crash in a few minutes of testing on Tiger either. But please feel free to re-open if this still happens to you. You may want to clear OS font caches and/or to try from a different user account, too.

indeed it only appears on one user account. When logging in with another (fresh) user account, the problem does not appear - also, meanwhile I have Leopard on the machine and Tiger now on an external disk. On Leopard (with a new user account) the problem doesn't appear either.

How do I empty the OS font-cache?

I'd just delete everything in ~/Library/Caches, /Library/Caches, and /System/Library/Caches, and reboot. But there are multiple "cache cleaner" utilities with nice GUIs to be found on MacUpdate or VersionTracker.
