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