OK.  I just installed those RPM's and I get the same thing.  If I use
the -fnew-abi option, which I wanted to use to get the latest
exception-handling model, I get the errors as I described in the last
e-mail to the list.

If I use the -fnew-exceptions option instead of -fnew-abi, the compiler
fails with an internal compiler error.

If I omit both -fnew-abi and -fnew-exceptions, the code compiles. 
However, I'm not sure whether it's using the right (thread safe)
exception model or not.

Jason Merrill:  The reason I CC'd this to you, is that I wanted to ask
if I need -fnew-exceptions or -fnew-abi for the thread-safe exception
model under Linux.

P.S.  The internal compiler error:
