Yes. I've got an approved patch for the current master:
https://gcc.gnu.org/pipermail/gcc-patches/2021-June/571593.html

For older releases, I consider relaxation of the assert.

Well, the problematic function is:

numpy/core/src/multiarray/einsum_sumprod.c.src: In function
=E2=80=98longdouble_sum_of_products_contig_three=E2=80=99:

So one should see a line directives in the function body that cause it ends
before it begins.=
