Since the GCC internal error matches its source code exactly
(https://github.com/gcc-mirror/gcc/blob/releases/gcc-7.5.0/gcc/cp/constexpr.c#L4644),
this internal error should be easily reproducible by looking at
work/.work.log.

Between GCC 7.5.0 and GCC 10, the (awfully long and hard to understand)
function cxx_eval_constant_expression has moved from line 3971 to line
5669, which means that much has changed in the last 3 years.

You should still try to reproduce this issue.  I suspect that there is
some "goto" in the file, as the code surrounding this internal error
says "case GOTO_EXPR".

By the way, in GCC 10 a GOTO_EXPR may also refer to a return statement.

This points almost directly to
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81942.
