FWIW, the problem after subversion id 236136 shows up when the trunk compiler
is built with the host compiler (4.3.4). I build compilers to build Spec using
the configuration option --with-advance-toolchain=at7.0 so that the libraries
and include files from the Advance Toolchain are used instead of the host
libraries and include files. The --with-advance-toolchain=at7.0 does not work
as well with a bootstrap compiler, so I tend to build a non-bootstrap compiler
to build spec objects with.
If I build it with the Advance Toolchain (AT 7.0), or presumably with a
bootstrap compiler from trunk, it builds the integer portion of Spec 2006 for
both reload and lra without error (building with the host compiler, 9 of the 12
SpecInt benchmarks would fail).
