Problem executing program against pixbuf 2.2.4 library

[Struan Bartlett <struan praguespringpeople org>]

Hello,

I have been developing a C program that uses the gdk pixbuf scaling
routines and the gdk-pixbuf xlib library for rendering.

My program compiles and runs successfully with gdk-pixbuf v0.17.0, using
gdk-pixbuf-config to provide the compiler arguments.

But with pixbuf 2.2.4, although my program compiles fine (using
pkg-config gdk-pixbuf-xlib-2.0 to provide the compiler arguments), when I
run my program the library throws some errors and segfaults.

I've traced the errors to where my program calls the gdk_pixbuf_new()
function, which is the first gdk function my program calls after calling
gdk_pixbuf_xlib_init().

Do you know why this should be?

Here's the output of 'make' using pixbuf 0.17.0:
