Error message, backtrace
The static analyzer crashes when run on the following file:
-----
void f(a) int a; { }
void g() { f(); }
-----
$ ~/llvm/build/bin/clang --analyze /tmp/a.c
clang-3.4: ../tools/clang/include/clang/AST/Expr.h:2196: const clang::Expr
*clang::CallExpr::getArg(unsigned int) const: Assertion `Arg < NumArgs && "Arg
access out of range!"' failed.
I include the backtrace in the attachment. The bug does not happen with
clang-3.0.</pre>
