             Bug #: 56992
           Summary: building Wine with -Og causes GCC to seg fault
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED

         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: jimpor...@gmail.com


GCC seg faults when building Wine with -Og.  The Wine developers pointed me at
http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction which helped me reduce
the problem down to the attached file (~14 lines).

$ gcc -Og -c testcase-min.c
testcase-min.c: In function ‘DnsHostnameToComputerNameA’:
testcase-min.c:13:1: internal compiler error: Segmentation fault
