Malloc error in GTK 3 apps


I have compiled and installed gtk+-3.3.18 on my system (based on
Slackware 13.37)

I have both gtk+-2 and gtk+-3 installed on my system.

All my gtk+-2 apps (gimp, firefox, etc.) work without a hitch.

However, for gtk-3, even though everything compiles ok, when I start
an app under gdb I get:

I guess on of my libraries has a problem with malloc, but which one?
