Since things seem to point to aliasing problems in the bison-generated 
files, I became suspicious to my previous statement about gcc-4.1.2pre 
fixing the problem. Turns out, that statement was wrong.

Gcc4.1.2pre is the current compiler in Debian/testing. Using that 
compiler and a fresh GiNaC 1.4 from CVS with one of the containter 
patches, I've just built a library where parsing is still broken.

It appears like the GiNaC library in Debian/testing was compiled with an 
older compiler and not rebuilt since the compiler was upgraded, since 
there, parsing works as expected.
