Managed to trig it with 7.7:

(Just had to switch from Image.load to the above construct.)
Image exists as http://www.mirar.org/DSC00354.JPG if anyone wants to try it. I'll see if I can get valgrind running tomorrow (remind me if I forget).
Hm, how did I get valgrind running again? It doesn't seem to link with anything, it complains about missing VALGRIND_MAKE_*.
Is there a special make target I forgot?
config.info: valgrind........ yes, using /usr/bin/valgrind -q --tool=memcheck
You have an old version of pike in combination with valgrind 3.x?

Yep, that's simple...
Can't seem to trigger it in valgrind_hilfe. :p Can trigger it in the normal run_hilfe. Evasive...
