llvm dev - Aug 2009 - [LLVMdev] can't build w/expensive checks

I get the error below when trying to build clang with expensive checks. 
  Works fine w/o these.  Is this a known problem?

This is on Ubuntu Hardy using this compiler:

regehr at john-home:~$ g++ --version
g++ (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu4)

Thanks,

John Regehr

Hi John,

this is a bug in libstdc++, and has been fixed here:
http://gcc.gnu.org/viewcvs?view=revision&revision=147599
If you can't pick up the fix, try compiling clang without the
-fno-rtti option.

Ciao,

Duncan.

Hmmm, this used to work, at least it didn't on Aug 07 on x86_64:
