[C] Mi date una mano a interpretare i log di Valgrind?

[Passy]

Ciao ragazzi...
Ho qualche problema a interpretare i log di Valgrind...
Mi date una mano

Non riesco a capire se il problema è nel mio codice o se derivi da glib...
Mi spiegate cosa significhi

... blocks are still reachable in loss ...

Grazie
