Bug 146358 – Segmentation Violations in GTK+ with optimisation on gcc-4.1.1

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Jeremy Barton 2006-09-05 00:57:40 UTC]

As mentioned in http://forums.gentoo.org/viewtopic-t-494802.html, compiling GTK+ optimised results in strange segmentation violations.  My consistent repro is with gmudix-1.0, connect to anything and try to highlight-copy test.

Compiled with -O3 on gcc-4.1.1 results in these SIGSEGVs, -O0 does not.  In the short term finding the max level and capping the optimisation in the ebuild would be good, as well as accelerating it upstream.

Which gtk+ version? Please, don't refer to forums.g.o. for bug descriptions, it makes bugzilla search useless.

[Comment 2 Jeremy Barton 2006-09-05 09:55:27 UTC]

Sorry, gtk+-2.8.19.
