# 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:

#

# https://bugzilla.gnome.org/enter_bug.cgi?product=glib
