           Summary: Fatal error while compiling on Compaq Tru64 UNIX
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: vlako at bart dot nl
                CC: gcc-bugs at gcc dot gnu dot org

Trying to compile gcc 3.3.2 source on a Compaq Tru64 UNIX V5.1 (Rev. 732) 
(ALPHA MACHINE) with the Compaq C V6.3-025 on Compaq Tru64 UNIX V5.1 (Rev. 
732) compiler (Compiler Driver V6.3-026 (sys) cc Driver).

After doing a successfull configure, and while doing the make bootstrap, the 
following error occured:

case "compare" in compare | compare-lean ) stage=2 ;; * ) stage=`echo compare 
| sed -e 's,^compare\([0-9][0-9]*\).*,\1,'` ;; esac;  if [ -f .bad_compare ]; 
then  echo "Bootstrap comparison failure!";  cat .bad_compare;  exit 1;  else  
case "compare" in  *-lean ) rm -rf stage$stage ;;  *) ;;  esac; true;  fi
Bootstrap comparison failure!
fix-header.o differs
*** Exit 1
Stop.
*** Exit 1
Stop.

I have talked to some people on EFNET about solving this problem, and they 
told me that this was probably a GCC bug.

Response would be appriciated.
If you need any further information, please contact me at vlako@bart.nl.

What options did you pass to configure? Was CFLAGS specified as anything in particular?

We have a reported successful build from 10/14: http://gcc.gnu.org/ml/gcc-testresults/2003-10/

Have you tried doing a 4-stage bootstrap? I once had a similar problem
of one file not comparing after stage 3 and one more stage fixed it.

I think this has something to do w/ generated files doing something
funny when bootstrapping from certain compilers.

Bootstrap should be fine with only 3 stages. It works something like this:
stage1: build gcc with native compiler (c compiler only)
stage2: build gcc with compiler built in stage1
stage3: build gcc with compiler built in stage2

compare .o files from stages 2 and 3.

If this fails, it means that given identical input, the compiler is producing
different output. That's a bug.

Anyhow, we're still waiting for the options you configured with, Karlo.

I want to say that Compaq's compiler is miscompiling the first stage which miscompiles 
only fix-header.o but the stage1 compiler compiles stage2 just fine otherwise and stage2 
compiles stage3 just fine. So this might not be a GCC bug.
Can you try with a new Compaq compiler?

This looks like a problem in the Compaq compiler.
