Extended Description

I am trying to compile a project that I am working on using clang. I've got the latest trunk from svn:

clang version 3.0 (trunk 134187)
Target: x86_64-apple-darwin10.7.4
Thread model: posix

I am encountering the error pasted below. Please let me know if I can provide any other information that can be useful:

Assertion failed: (isa(Val) && "cast() argument of incompatible type!"), function cast, file llvm/include/llvm/Support/Casting.h, line 194.

Preprocessed input that crashes clang
As requested.

Reduced testcase:

template
class Templated {
struct Exception {
};
void exception() {
try {
} catch(Exception e) {
}
}
}

reproducable with "clang -cc1 -x c++ pr10232.cpp".

[DougGregor]

Fixed in Clang r134515.
