I think this relates to the changes jicama did yesterday. Maybe he can help us
fix it?

--- Comment #7 from David Binderman  ---
Reduced C++ code seems to be:

template  struct integral_constant {
  static constexpr int value = __v;
};
template  constexpr long find_index() { return 1; }
template 
using find_index_checked = integral_constant()>;
template  class Trans_NS_mpark_variant {};
template  void get(Trans_NS_mpark_variant);
template  void get(Trans_NS_mpark_variant v) {
  get::value>(v);
}
void TestBody() {
  Trans_NS_mpark_variant w;
  get(w);
}

The bug first seems to occur sometime between git hash 
b58dc0b803057c0e, dated 20210429, and 17f2908fcf058e14, dated
20210430.

I have a poor record with git bisect, so I will leave that 
to someone else more competent.

gzipped C++ source code

I see a similar error. Preprocessed C++ source code attached.

I will reduce the code, using cvise.

Preprocess

sorry. the file was too large.

It looks like it is an issue related to constexpr evaluation.
