Is this a regression?

[ncharlton02]

No - same issue on 0.14.4

[ncharlton02]

Here is a minimal test case:

pub type Foo = generic::Foo<u32>;

mod generic {
    pub struct Foo<T> {
        foo: T,
    }
}

mod structure {
    #[repr(C)]
    pub struct Foo{
        foo: u32
    }
}

Note: this only panics when the language is set to C

I see, I think that's "just" #7... We're probably getting confused about what of the two types we're referencing. We could potentially fail more gracefully here without much issue.

Closing as a dupe of #7... You might want to /// cbindgen:ignore the generic type or such, I agree it's an unfortunate limitation.
