This C program crashes on my system:

----------------------------------------------------
#include <gdk-pixbuf/gdk-pixbuf.h>

/* XPM */
static const char * close_xpm[] = {
"12 12 2 1",
" 	c None",
"+	c #000000",
"            ",
"  +    ++   ",
"  ++  ++++  ",

"   ++++++   ",
"   ++ ++++  ",
"  ++   ++++ ",
"  +     ++  ",
"            "};

int
main()
{
    (void) gdk_pixbuf_new_from_xpm_data(close_xpm);
    return 0;
}
----------------------------------------------------

I compile it this way with gcc 2.96-112.7.2:

    gcc -g -Wall gdk_pixbuf_new_from_xpm_data.c \
		`pkg-config --cflags --libs gtk+-2.0`

The compiler displays no warnings.  The pkg-config command writes this:

    -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include
    -I/usr/include/atk-1.0 -I/usr/include/pango-1.0
    -I/usr/X11R6/include -I/usr/include/freetype2 -I/usr/include/glib-2.0
    -I/usr/lib/glib-2.0/include  -Wl,--export-dynamic -lgtk-x11-2.0
    -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangoxft-1.0
    -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0

Running the a.out executable displays this:

    (process:12732): GdkPixbuf-WARNING **: Can not open pixbuf loader
    module file '/etc/gtk-2.0/gdk-pixbuf.loaders': No such file or
    directory
    Segmentation fault (core dumped)

The only file in /etc/gtk-2.0 is gtk.immodules and it only contains
lines that start with '#'.

The call stack reported by GDB (5.2) after the SIGSEGV is this:

    #0  0x402c883a in gdk_pixbuf_new_from_xpm_data ()
       from /usr/lib/libgdk_pixbuf-2.0.so.0

	rtld_fini=0x4000d2fc <_dl_fini>, stack_end=0xbffff5ac)
	at ../sysdeps/generic/libc-start.c:129

When the XPM lines (including the /* XPM */ comment) are written
to a file called close.xpm, Electric Eyes 0.3.12 has no problem
displaying it.  Another program of mine, written for GNOME 1.4,
had no problem loading that XPM either.
