[Bug other/26715] New: boostrap comparison failure (stage2?) during make bootstrap on solaris8 only?

[chris dot pitchford at newsint dot co dot uk]

Hi all,

I've been trying upgrade our C environment on our solaris boxes to GCC4.1

Currently we're using GCC 3.4.2 from Sun Freeware's online packages.
$ gcc --version
gcc (GCC) 3.4.2
...

Using the same ./configure options on 4 clean sparc Solaris systems (running
2.6, 7, 8 and 9) systems I find that the "make bootstrap" fails on solaris 8
only.

I'm configuring the source as:
  cd /build/gcc/compiled ;
  CONFIG_SHELL=/bin/ksh  "/build/gcc-4.1.0/configure" \
        --prefix="/opt/gcc"             \
        --with-as=/usr/ccs/bin/as       \
        --with-ld=/usr/ccs/bin/ld       \
        --disable-nls                   \
        --enable-libgcj                 \
        --enable-languages=c,c++,objc,java

make bootstrap fails on my solaris8 system complaining:

Bootstrap comparison failure!
./integrate.o differs
cp/semantics.o differs
build/gengtype.o differs
make[1]: *** [gnucompare] Error 1
make[1]: Leaving directory `/build/gcc/compiled/gcc'
make: *** [bootstrap] Error 2

using 'hexdump' I have compared the two six files that differ:
integrate.o             0006000 0000 0723 000f 0300 0260 1c23 750a 6469
stage2/integrate.o      0006000 0400 0723 000f 0300 0260 1c23 750a 6469

cp/semantics.o          0028c00 0000 8028 0100 0714 0000 0000 0000 8828
stage2/cp/semantics.o   0028c00 0400 8028 0100 0714 0000 0000 0000 8828

build/gengtype.o        0014c00 0000 b418 0100 0057 1800 00b4 1800 00ec
stage2/build/gengtype.o 0014c00 0400 b418 0100 0057 1800 00b4 1800 00ec

There is a one bit difference between the pairs!

I'm sorry if I've left out information, I'm not sure what I need to provide
here. I've checked the pre-requisites and I believe I match them all.

It all works fine on my solaris 2.6, 7 and 9 systems. Only Solaris 8 seems to
be suffering at the moment. For good measure I have installed the latest
recommended patch cluster from Sun but it has not made a difference.

More of a problem is the failure occurs about 6.5 hours into the compile.

Finally, I'm currently only working with sparc Solaris systems, I've not got
access to any intel sparc systems to test this under solaris8/x86

Thanks

Chris

Pretty weird indeed.  What's the bootstrap compiler on the Solaris 8 machine? 
Is it the same as on the other machines?  Could you try a C-only bootstrap with
it and with another one?

Currently the only C compiler on the box is GCC 3.4.2 which was downloaded from
Sunfreeware.com Is this the bootstrap compiler? To be honest this project is
the first time I've tried to compile GCC, I've always previously used
sunfreeware's or my distro was bundled with GCC!

Am I right in thinking the compilation process is.. use system CC to make an
interim GCC, then use that to compile the full GCC?

The bootstrap compiler is the compiler that compiles GCC during stage #1 of the
3-stage bootstrap.  During stage #2 and stage, #3 GCC compiles itself.

Do you have another C compiler than GCC 3.4.2 installed on the box?
