 Hello,
 
 gcc 3.1 is quite old. Can you reproduce this error on a newer version  
 (ie 3.2.3)? Thanks,
 
 Dara

I have try it without -march=athlon and/or a gcc build with default setup -- same problem when I tries to bootstrap with -O3 
Why is it saying 3.1 (20020212)?

The problem have be there for more that a week!
>How-To-Repeat:
build gcc from CVS (20020513)

../gcc/configure --enable-languages='c,ada,c++,f77,java,objc' --enable-threads=posix --enable-long-long --disable-nls 

(time make bootstrap) && (cd gcc/;time make gnatlib_and_tools)
or
(time  make  CFLAGS='-march=athlon -pipe -O2' STAGE1_CFLAGS='-march=athlon -pipe -O2'  BOOT_CFLAGS='-march=athlon -pipe -O2' bootstrap ) && (cd gcc/;time make CFLAGS='-march=athlon -pipe -O2' STAGE1_CFLAGS='-march=athlon -pipe -O2'  GNATLIBCFLAGS='-march=athlon -pipe -O2'  BOOT_CFLAGS='-march=athlon -pipe -O2' gnatlib_and_tools)


and rebuild it with -O3

../gcc/configure --enable-languages='c,ada,c++,f77,java,objc' --enable-threads=posix --enable-long-long --disable-nls --prefix=/home/lasj/Test1 

(time make  CFLAGS='-V -O3' STAGE1_CFLAGS='-O3'  BOOT_CFLAGS='-O3' bootstrap ) && (cd gcc/;time make CFLAGS='-O3' STAGE1_CFLAGS='-O3'  GNATLIBCFLAGS='-O3'  BOOT_CFLAGS='-O3' gnatlib_and_tools)
or
(time make  CFLAGS='-march=athlon -g  -pipe -O3' STAGE1_CFLAGS='-march=athlon -g  -pipe  -O3'  BOOT_CFLAGS='-march=athlon -g  -pipe  -O3' bootstrap ) && (cd gcc/;time make CFLAGS='-march=athlon -g  -pipe -O3' STAGE1_CFLAGS='-march=athlon  -g  -pipe -O3'  GNATLIBCFLAGS='-march=athlon  -pipe  -g -O3'  BOOT_CFLAGS='-march=athlon  -pipe  -g -O3' gnatlib_and_tools)
