Bug#1053826: gcc-12: internal compiler error with template specialization on floating point non-type-param in C++20 mode
This is fixed in GCC 13, available in testing and unstable. Doesn't look like a
regression, so it's unlikely to be backported.

Hello.
The following piece of code generates a compiler error with gcc-12 in C++20
mode:
template
struct F {
static double foo() { return D; }
};
template
struct F {
static double foo() { return 1.0; }
};
int main()
{
return F::foo();
}
gcc-13 in sid does compile this correctly. on godbolt only gcc-trunk, not
gcc-13, compiles this, so from my point of view, it may be a Debian patch in
gcc-13 in sid, which fixes this.
The error (on gcc-12 from sid) is this:
$ g++-12 -std=c++20 -o test test.cpp
test.cpp: In function ‘int main()’:
