the latest SVN gcc also breaks. Disabling optimization when compiling 
GiNaC makes the bug vanish (no matter what version).

But the interesting news is: I compiled bison version 2.3 and used it 
for the compilation of GiNaC. That removes the bug also! Before I used 
the installed bison version 1.85.

So my guess is, that bison has some issues with the new gcc 4.1. Can 
anybody reproduce my findings?
