I haven't looked into that since we talked about it before.
I thought you were going to investigate?

I've seen several other problems with gcc-4.5 on vax:
 - ld crashes (run natively, it works fine as a tool on an amd64 host)
 - vi dumps core on startup
 - c++ exceptions crash in the exception-handling code

I haven't investigated any of these.  it's rather depressing.
