[./build/libglusterfs/src/y.tab.c:2104]: (error) Memory leak: cmd
[./libglusterfs/src/md5.c:306]: (error) Resource leak: f
[./xlators/debug/io-stats/src/io-stats.c:1396]: (error) Possible null pointer dereference: this - otherwise it is redundant to check if this is null at line 1402
[./xlators/cluster/stripe/src/stripe.c:3597]: (error) Memory leak: dup_str
[./xlators/debug/trace/src/trace.c:2426]: (error) Possible null pointer dereference: this - otherwise it is redundant to check if this is null at line 2429

These appear in rarely hit error cases or test/demo code so nothing
serious, in fact.
