Subject: [Patch] NULL pointer dereference in sound/synth/emux/soundfont.c
Date: Tue, 30 May 2006 22:18:16 +0200 [thread overview]
Message-ID: <1149020296.29430.4.camel@alice> (raw)
hi,
this is about coverity id #100.
It seems the if statement is negated, since the else branch calls
remove_info() with sflist->currsf as a parameter where it gets
dereferenced.
