             Bug #: 14608

           Summary: --detect-odr-violations doesn't work with GCC 4.7

           Product: binutils

           Version: unspecified

            Status: NEW

          Severity: normal

          Priority: P2

         Component: gold

        AssignedTo: address@hidden

        ReportedBy: address@hidden

                CC: address@hidden

    Classification: Unclassified





On Linux/ia32, with GCC 4.7, I got



address@hidden testsuite]$ /usr/gcc-4.7.1/bin/g++ -W -Wall -Werror

-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -fmerge-constants -o

debug_msg_so.err -Bgcctestdir/ -Wl,--detect-odr-violations -o debug_msg_so

debug_msg.so odr_violation1.so odr_violation2.so

address@hidden testsuite]$ 



FAIL: debug_msg.sh



It passed with GCC 4.2:



address@hidden testsuite]$ /usr/gcc-4.2/bin/g++ -W -Wall -Werror

-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -fmerge-constants -o

Linux/x86-64 is OK.
