Valgrind claims there is unfreed memory. Is this bad?

Question

Valgrind gives me the following leak summary on my code. However, I have freed all malloc\'ed memory. Is this a bad thing, or is this normal? My program is in c.

Answer 1

These are not leaked and nothing to be concerned about. The memory was probably allocated by the C library. If you really want to know where they were allocated run with --leak-check=full --show-reachable=yes.
