           Summary: "lemon" creates bogus ".c" sources files which crash GCC
                    3.3.x
           Product: Wireshark
           Version: 0.99.5
          Platform: PC
               URL: http://mail-index.netbsd.org/tech-
                    pkg/2007/02/03/0004.html
        OS/Version: NetBSD
            Status: NEW
          Severity: Major
          Priority: Medium
         Component: Wireshark
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: tron@xxxxxxxxxx


Build Information:
N/A

The tool "lemon" include in the "wireshark" distribution creates ".c" files
with bogus line numbers:

#line 917 "dtd_grammar.c"
        break;
      case 19:
#line 1853321060 "./dtd_grammar.lemon"
{
  yy_destructor(15,&yymsp[-2].minor);
  yy_destructor(16,&yymsp[0].minor);
}

Those line numbers break the compilation with GCC 3.3.x:

Patching "lemon.c" not to write the line numbers to the generated ".c" files
fixes the problem. But it doesn't explain why the bogus line number was
generated in the first place.
