Hi
You can use the option
--gen-suppressions=no|yes|all print suppressions for errors? [no]
This will generate a suppression block after the usual stacktrace, something
like this:
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: reachable
fun:malloc
fun:main
}
If you do reuse the generated suppressions then you will need to generate some
sort of unique name.
A+
