id3lib stack smashing



There is ubuntu bug report against id3lib "libid3 crashes (stack
smashing) when reading VBR MP3 file"[1]. I am able to reproduce this on
ubuntu but not on Fedora and I do not understand why. The patch[2] looks
like it is doing the right thing but there is not stack smashing detected
using the Fedora version (even on ubuntu). I have looked at the ubuntu
build logs[3] and it uses completely different compiler flags. Is one of
those flags the reason for not seeing the stack smashing on Fedora?
