           Summary: [3.4 regresssion] Spurious bootstrap comparison failures
                    on sparc-sun-solaris
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: build
          Severity: critical
          Priority: P2
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ehrhardt at mathematik dot uni-ulm dot de
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: sparc-sun-solaris2.9
  GCC host triplet: sparc-sun-solaris2.9
GCC target triplet: sparc-sun-solaris2.9

I've been unable to do a clean bootstrap on sparc-sun-solaris with
3.4 for quite some time now. The problem is that I keep getting
spurious bootstrap comparison failures for some files. The files that
are affected seem to vary depending on the circumstances of the bootstrap.

However, the differences found are always due to an embedded temporary
file name in the object. The bootstrap comparison seems to expect this
difference but expects it at the beginning of the object file.
With my environment these differences appear somewhere in the middle
of the object file.

To illustrate this I ran fix-header.o and stage2/fix-header.o through
od -bc. The diff -u of these files looks like this:
