Bug 136002 – svgdisplay from kde-base/ksvg-3.5.2 crashes when using fonts after gcc version switch

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Martin von Gagern 2006-06-07 15:16:53 UTC]

I recently switched from gcc 3.3 to 3.4. I already encountered bug 135194 and bug 91437 and remerged dev-libs/libsigc++, dev-cpp/glibmm and dev-cpp/gtkmm. I alsro remerged ksvg. Still I get runs like the following.

A file with two text elements crashed immediately:
Font::load(), loading /usr/share/fonts/TTF/Vera.ttf for requested font "sans-serif"
*** glibc detected *** double free or corruption (!prev): 0x080599f0 ***
KCrash: Application 'svgdisplay' crashing...

The same file with one text element removed crashed when closing the window:
Font::load(), loading /usr/share/fonts/TTF/Vera.ttf for requested font "sans-serif"
*** glibc detected *** free(): invalid pointer: 0x080599d8 ***
KCrash: Application 'svgdisplay' crashing...

Without the text elements everything works fine, so I guess it has to have something to do with text or fonts.

But which of the 155 deps of ksvg should I rebuild?
How can I tell which of the 51 libs printed by ldd is a C++ lib affected by the changed ABI?

Looking at the output from ldd, I find that libgcc_s.so.1 is in the gcc 3.3.6 directory, not 3.4.6. Even though I did run fix_libtool_files.sh and remerged the app afterwards. Is there something wrong here?

OK, this rebuilt most of my KDE, among others, took more than a day, but afterwards it really worked.

It is still annoying. Would be great if the compiler version used would be saved in /var/svg/package so that a future revdep-rebuild version could emerge the correct files after an ABI change. But I believe that already has been mentioned somewhere, so let's close this one here.

It was of course /var/db/pkg/ that I meant.
Should not write bug comments this early in the morning...
