            Bug ID: 65931
           Summary: [5/6 regression] dsymutil assertion failure building
                    libgnat-5.dylib
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: howarth.at.gcc at gmail dot com, iains at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-apple-darwin14.3.0
            Target: x86_64-apple-darwin14.3.0
             Build: x86_64-apple-darwin14.3.0

For about two weeks (thus affecting both the gcc-5 branch and mainline), Ada
bootstrap on Mac OS X 10.10.3 is broken:

cd rts; dsymutil libgnat-5.dylib
Assertion failed: (linked_addr_pos != line_table_map.end()), function
FixReferences, file
/SourceCache/dwarf_utilities/dwarf_utilities-121/source/DWARFdSYM.cpp, line
3883.
/bin/sh: line 1: 85928 Abort trap: 6           dsymutil libgnat-5.dylib
make[3]: *** [gnatlib-shared-darwin] Error 134

This is dsymutil from dwarfutils-121.  I haven't yet checked if gcc's DWARF
output
changed in a way dsymutil cannot handle or dsymutil was upgraded (from Mac OS
10.10.2 to .3) adding some bogus check.

Even if dsymutil hasn't been upgraded, it might still be Apple's bug anyways...
Have you filed a radar for this yet?

Good, that helped quite a lot.

Thanks for the info.

I did provide what I was asked for. Since then I don't have any news.
