This looks like it's from LLVM. Is it?

[Quuxplusone]

This looks like .

The issue here is that we aren't passing in the VTT parameter when nececssary.

See also rdar://problem/7495203 clang C++ asserts when compiling auto_gdb_interface.cpp (if you can).

[Quuxplusone]

seems to work with recent clang:

clang version 1.1 (trunk 93632)
Target: x86_64-unknown-freebsd8.0
Thread model: posix
pes ~$ clang -c 000.cc && echo succes
succes

I am not sure if the issue has been fixed or just covered though

[Quuxplusone]

Ok, lets call it fixed then.
