# 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://gitlab.gnome.org/GNOME/glib/issues/new { gnutls-init-calloc Memcheck:Leak match-leak-kinds:reachable fun:calloc ... fun:gtls_gnutls_init } { gnutls-init-realloc Memcheck:Leak match-leak-kinds:reachable fun:realloc ... fun:gtls_gnutls_init } { g-tls-backend-gnutls-init Memcheck:Leak match-leak-kinds:reachable fun:g_once_impl fun:g_tls_backend_gnutls_init } { p11-tokens-init Memcheck:Leak match-leak-kinds:reachable fun:calloc ... fun:create_tokens_inlock fun:initialize_module_inlock_reentrant } #
