I believe I'm hitting (what I'm pretty sure is) this with same bug GCC 4.6
trunk as well. Can you apply the patch to lto-streamer-out.c on the 4_6 branch
as well? Thanks!

I'm always relucant in backporting this kind of fixes as the LTO state is
so different on branches. Can you confirm that backporting this fix fixes
problems for you? I ask because type-decls do not survive on the 4.6 branch
AFAIK.

Applying the patch does allow DWARF serialization to get further, but now it
dies here:
internal compiler error: in add_AT_specification, at dwarf2out.c:7536
It looks like this problem (hiding beneath the original) is related to PR47839,
whose fix was fortran front-end specific.
Should I just file a new bug and reference these other bugs?

No, it just means that -g is (expected) somewhat broken still in GCC 4.6.
Only with GCC 4.7 I spent considerable time trying to solve all ICEs
in that area.
It's not worth cherry-picking selcted fixes because they usually expose
other bugs.
Richard.
