             Bug #: 54671
           Summary: gcc 4.7.2 -Wl,--no-ctors-in-init-array causes binutils
                    test failure, works with 4.7.1
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: other
        AssignedTo: unassigned@gcc.gnu.org

broken output file and generating makefile

binutils-2.22/gold has an extra test failure when built with gcc 4.7.2.  This
is the offending command:

gcc -Bgcctestdir/ -Wl,--no-ctors-in-init-array -Wl,-O1,--as-needed -o
broken_by_gcc_472 a.o

With 4.7.1, the test passes.  I have put this in the 'other' category as no
compilation seems to be taking place.

In the attachment, you'll find output files generated with 4.7.2 and 4.7.1 to
compare, hopefully the second is obviously broken.  Also there is a Makefile to
run the offending command, and preprocessed source for the object file being
used.

Thank you, hope this is enough to find/fix the error.

Neil Cahill.
