1 # GLib Valgrind suppressions file
3 # This provides a list of suppressions for all of GLib (including GIO), for all
4 # Valgrind tools (memcheck, drd, helgrind, etc.) for the false positives and
5 # deliberate one-time leaks which GLib causes to be reported when running under
6 # Valgrind.
8 # When running an application which links to GLib under Valgrind, you can pass
9 # this suppression file to Valgrind using --suppressions=/path/to/glib-2.0.supp.
11 # http://valgrind.org/docs/manual/manual-core.html#manual-core.suppress
13 # Note that there is currently no way for Valgrind to load this automatically
14 # (https://bugs.kde.org/show_bug.cgi?id=160905), so the best GLib can currently
15 # do is to install this file as part of its development package.
17 # This file should be updated if GLib introduces a new deliberate one-time leak,
18 # or another false race positive in Valgrind: please file bugs at:
20 # https://bugzilla.gnome.org/enter_bug.cgi?product=glib
