search for: __gxx_personality_v0

linux fedora f9 x86_64 llvm-2.4 I tried building a bunch of my python modules (which compile to shared libraries) using llvm-c++ instead of gnu c++. When the program runs, I see these messages: python: Symbol `__gxx_personality_v0' causes overflow in R_X86_64_PC32 relocation Ideas?

Manual unwinding, here I come. :-( I was going to say the interpreter doesn't either, but then I recalled it JITs when it can. I don't know how to call into libc from the interpreter to test that.
