------- Comment #2 from rguenth at gcc dot gnu dot org  2010-07-20 12:20 -------
Confirmed.

The issue is that we throw away fields needed for debug info during
free-lang-data when we are not going to generate debug info, but we
crash when those are not available.

------- Comment #3 from rguenth at gcc dot gnu dot org  2010-07-20 12:26 -------
Basically this way you can reproduce all (or most of) formerly fixed -g
issues with LTO.  Unless we decide to stream this information always this
won't be fixed (adding random workarounds in dwarf2out.c doesn't sound good).

No longer reproduces during mozilla build.  
Richi, I think we could close this?

This seem to work now. Richi, I think you fixed this some time ago by not
zeroing the fields by default?

Hmm, shall we just trim down freeing of lang datastructures to not depend on -g
or simply refuse link LTO objects compiled with -g0 with -g (and convince
Mozilla to update their Makefile?)
