I'm not sure about last analysis of Andrew Pinski, but I have tested todays
gcc3.4 and it stills shows this bug, so I have finally writtin small script
which is able to duplicate this bug. Mea culpa that I have not provided it more
early...

thinkpad:/tmp$ cat pchbug.sh 
#!/bin/sh
set -x
wget http://mico.org/mico-2.3.11.tar.gz
rm -rf mico
tar -xzvf mico-2.3.11.tar.gz
cd mico
./configure --disable-static --disable-optimize
sed -e 's/-Wall/-Wall -DFAST_PCH/g' < MakeVars > MakeVars.new
cp MakeVars.new MakeVars
cd include
mkdir CORBA.h.gch
c++  -I../include  -Wall -DFAST_PCH   -DPIC -fPIC  -c CORBA.h -o CORBA.h.gch/O0pic
c++  -I../include  -Wall -DFAST_PCH   -c CORBA.h -o CORBA.h.gch/O0
cd ..
cd admin
make
cd ../orb
make .depend
c++  -I../include  -Wall -DFAST_PCH   -DPIC -fPIC  -c orb_pch.h
make


Please also note that while compiling orb_pch.h I also get these strange error
messages, but compilation continues well and produce precompiled header file:

+ c++ -I../include -Wall -DFAST_PCH -DPIC -fPIC -c orb_pch.h

thinkpad:/tmp/mico/orb$ ls -la orb_pch.h.gch

Please let me know if I can help more with debuging this issue.

Thanks,
Karel
