Created attachment 303883 [details] backtrace the program works fine far as I can tell, but once you close the window and when the program is ran from terminal, you see "Segmentation fault" after some unrelated font not found messages note: the attached backtrace is with all direct dependencies of gv, and gv itself, built with -ggdb.

Created attachment 303887 [details, diff] patch Fixes the crash for me. I'm not sure why I wasn't able to reproduce it earlier when you told me about it. Also strange is that this code is exactly the same in 1.5.
FTR, the new patch works fine
http://lists.x.org/archives/xorg-devel/2012-March/029639.html Since the patch is already on xorg-devel ML and got some reviews, pushed this to tree +*libXaw3d-1.6.1-r1 (05 Mar 2012) + + 05 Mar 2012; Samuli Suominen <ssuominen@gentoo.org> + +libXaw3d-1.6.1-r1.ebuild, +files/libXaw3d-1.6.1-use_after_free.patch: + Fix use after free in DestroyAllIM (causing segmentation fault in app-text/gv + exit) wrt #406487 by Matt Turner
