I was looking at the pidgin.im trac and someone found some memory leaks with cppcheck so i ran the VLC code against it and it found the following. Mind you I don't claim to know what the errors\warning mean, but I just hope to help.
[../modules/video_chroma/i420_yuy2.c:59]: (Error) Invalid number of character ({). Can't process file.
[../modules/video_filter/wall.c:425]: () Warning: Division with signed and unsigned operators
[../modules/video_filter/wall.c:426]: () Warning: Division with signed and unsigned operators
[../src/misc/threads.c:1323]: (Error) Memory leak: nfo
Also this is with the option to turn off possible false positives, which I'd estimate there were about 200.
