Package: libgtk2.0-0 Version: 2.6.10-1 Severity: important
When running Freeciv 2.0 (currently in debian unstable, also downloadable from http://freeciv.org/) under valgrind, I get a number of warnings and errors inside the glib and gdk libraries. Some of these are actual errors that look like they could cause a crash under the right circumstances. The natural tendancy is probably to blame the calling code for these errors rather than the library, but I don't see how this could be the case here. In fact several of the major bugs (an invalid read inside gtk_parse_args) can be reproduced using the program below. Other bugs aren't included here but the full output of the valgrind runs can be found at Valgrind run on bug.c: http://freeciv.org/~jdorje/gtk-bug.txt Valgrind run on Freeciv 2.0 (compiled from source): http://freeciv.org/~jdorje/output-2.0 /* Copy this code into a file bug.c.
