Thanks for the last reply!
I was checking the simplest glib program continually. Now, I found the
leak-check could not give a summary of used suppression specifically. In my
default.supp file, there is a rule named "glib type registry", which is used
to suppress 20 blocks leak report. As I commented this rule, the 20 blocks
suppressed report will turn into 20 blocks possibly lost report. At the end
of execution, Valgrind only prints out one line for a rule named dl-hack3-1,
which is also used to suppress some errors, but Valgrind does not prints any
more information about "glib type registry" used by leak checking as manual
says.
I wander that if I missed any trick to get exact information about
suppression used by leak-check?
There is another thing I wander to know. While I commented the "glib type
registry" rule in the suppression file, Valgrind described the error
beginning with "800 bytes in 20 blocks are possibly lost in loss record 1 of
5". In my opinion, "1 of 5" means there were five leak errors, and this is
one of these, but Valgrind did not give out other four error further. where
are these four errors?
- Below is the "glib type registry" suppression rule.
# Glib stores pointers in an integral type. Bug#231989
{
glib type registry
Memcheck:Leak
fun:calloc
fun:g_malloc0
fun:type_node_any_new_W
}
- Below is the report used the "glib type registry" suppression rule.
