This problem seems to be caused by a bug in gcc 3.2. I have send a bugreport 
to the gcc development team almost a month ago (#7730). Hopefully, it will be 
fixed in gcc 3.3.

You could try using the -mno-omit-leaf-frame-pointer and/or *not* using the 
-fomit-frame-pointer gcc flags. I'm currently using the following patch which 
also seems to 'fix' this problem (see attachment).

bye,

ewald
