             Bug #: 53472
           Summary: contrib/compare-debug should strip out .comment
                    section
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com

Now, as to why for me BUILD_CONFIG isn't bootstrap-debug: configure.ac
activates this by default, but then checks if contrib/compare-debug
actually works for comparing a debug and non-debug .o file.  And for
SuSE systems it doesn't, because our system compilers encode some command
line options (among them -g) into a special .comment section.

Any chance you could adjust the script to strip out the .comment section
you mentioned elsewhere, so that you get faster bootstrap with
bootstrap-debug testing too?
