Yes. I got the information from Martin that they are using
GdkPixbufLoader in LispWorks, and he provided me with a corresponding
C source, a modification of which I used for filing the GDK bug that I
have mentioned.

I did this back then with LispWorks PE 6.1.1 but I might try it again
if there is a newer version available. These were the results I gave
to Martin:

I have a newer version on my system: libgdk_pixbuf-2.0.so.0.3100.1
I have already created it with debugging symbols but got stock at some
point of debugging, Maybe I will try it again in order to find what is
the difference between regular 64bit and 32bit on my system.

It all looked fine back then.

Maybe you could try to run the small programs I provided as
attachments to the GDK bug report? They should just work on your 64bit
system.

Many thanks!
