Panic while building [surfer project](https://surfer-project.org/) bindings

Originating from an issue hit with maturin - https://github.com/PyO3/maturin/issues/2431

While attempting to build the bindings for libsurfer,
using cbindgen 0.27.0, with the following config:

language = "C"
no_includes = true
sys_includes = []
defines = {}
include_guard = ""
pragma_once = false
cpp_compat = false

The following panic occurs:

$ cbindgen -c cbindgen.toml -vv

Reproduce the failure by building the libsurfer bindings with cbindgen 0.27.0, the shown cbindgen.toml configuration, and cbindgen -c cbindgen.toml -vv. Start with the verbose output and the related maturin issue; done means the command no longer panics for this input.
