Benjamin,
no, I'm sorry, I don't have cc1plus's lying around. I can see a simple
way to get differences in object file/debug info: readelf shows this for
the same file compiled with either 3.3 or 3.4:

tmp/gg> readelf --debug-dump=info x.33.o | grep _M_
     DW_AT_name        : _M_
     DW_AT_name        : (indirect string, offset: 0xc9): _M_references
     DW_AT_name        : (indirect string, offset: 0x4b): _M_facets
     DW_AT_name        : (indirect string, offset: 0xd7): _M_facets_size
     DW_AT_name        : (indirect string, offset: 0x7c): _M_names
tmp/gg>
tmp/gg> readelf --debug-dump=info x.34.o | grep _M_
     DW_AT_name        : _M_

and likewise

tmp/gg> readelf --debug-dump=info x.33.o | grep inner
     DW_AT_name        : (indirect string, offset: 0x55): inner
     DW_AT_MIPS_linkage_name: (indirect string, offset: 0x5b):
_ZN3bug5outer5inneraSERKS1_
     DW_AT_name        : (indirect string, offset: 0x55): inner
     DW_AT_name        : (indirect string, offset: 0x55): inner

tmp/gg> readelf --debug-dump=info x.34.o | grep inner
     DW_AT_name        : (indirect string, offset: 0x1e): inner


So there is simply some information missing. Janis may be able to make use
of this difference to find the causing patch. I'll CC: her.

Regarding the state change of PRs: no problem, and thanks for cooperation :-)
