Description
Hi, i'm unable to use header(...) and header_contents(...) for the same bindings generation, libclang always panics.
Input C/C++ Header
Header content doesn't matter, it even happen when headers are empty.
Bindgen Invocation
fn main() {
bindgen::builder()
.header("bar.h")
.header_contents("foo.h", "")
.generate()
.expect("Unable to generate bindings");
}Actual Results
thread 'main' panicked at 'libclang error; possible causes include:
- Invalid flag syntax
- Unrecognized flags
- Invalid flag arguments
- File I/O errors
- Host vs. target architecture mismatch

Expected Results
I just expected a bindings result, not a panic.
