preprocessed file

When compiling GNU MPFR on a parisc machine (gcc61.fsffrance.org), I get an ICE
(see below). This can be reproduced with:

  /opt/cfarm/release/4.4.1/bin/gcc -O3 tconst_pi.i

where tconst_pi.i is attached. The bug is not reproducible with -O2 only. I
couldn't find a similar bug report (including among the closed bugs), and there
doesn't seem to be a more recent GCC version on this machine.

This also occurred with MPFR 3.0.0 and 3.1.0 (at least).
