This is not a bug. The GNATS entry should be closed.
The snapshot code used for comparison was the CodeSourcery RPM which is
targeted to "i386-pc-linux-gnu", while the 2.95.2 compiler was targeted
to "i686-pc-linux-gnu", and code was run on Pentium II and Pentium III
systems. Compiling with the -mcpu=i686 flag, or compiling the snapshot
code with the i686 target yields code similar to the 2.95.2 compiler.
Thanks to Bernd Schmidt for pointing me in the right direction.
