[Bug pch/29353] New: ICE: testsuite failure with max-unswitch-insns=1000 max-unswitch-level=4 max-aliased-vops=10000

[micis at gmx dot de]

When I bootstrap gcc with the commands given below I get a testsuite failure
in libstdc++-v3/testsuite/25_algorithms/rotate/1.cc
It might be a pch problem, since that ice does not occur if I compile the
testsuite file without using any library

Command to build and test gcc:

export CFLAGS="-O3 --param max-unswitch-insns=1000 \
 --param max-unswitch-level=4 --param max-aliased-vops=10000"

export CXXFLAGS=$CFLAGS

../gcc-4.2-20060930/configure --prefix=/usr/local/gcc42d --program-suffix=42d \
 --with-arch=opteron --enable-languages=c,c++ --enable-__cxa_atexit \
 --disable-nls --enable-threads=posix --disable-multilib --enable-checking

make -j4 bootstrap

make check -j -k
