The suppression in question is used for an allocation that happens in libc:
{
MEMCHECK-LIBC-REACHABLE-1
Memcheck:Leak
match-leak-kinds: reachable
fun:malloc
obj:*/lib*/libc.so.7
obj:*/lib*/libc.so.7
obj:*/lib*/libc.so.7
fun:vfprintf_l
}
Other than that, valgrind doesn't report any leaks. Although you tested on
14.1, I strongly suspect that it's the same false positive there.
