Hi again!
New findings are in. It appears that it has nothing to do with optimization in GCC (3.3.3). When I start a squeak (any image) it simply fails on the described primitive. BUT... if I start *another squeak* with same or another image then it works in *that* squeak!
Hehe... sounds to me there is some funkiness going on with some shared whatchamacallits.
Since I just discovered that SSE2 is very shaky on a Pentium-M I need to rebuild my whole laptop (sigh) over the night - perhaps the problem goes away then.
regards, Göran
