That even passes the 'make check'; but I didn't dig into all the corners
yet.

I have identified two issues related to indirect function calls into
built-in functions of AWK. The attached script contains both scenarios
to
reproduce the identified problems.
GNU Awk 5.3.1, API 4.0, (GNU MPFR 4.0.2, GNU MP 6.1.2)
downloaded from ezwinports
How do you run this script?
You have to change his 'if (0)' to 'if (1)'.
I've spent almost all day debugging this. The problem is very
much a corner case, but there are some things that need fixing.
It's still a work in progress, but having more eyes on it may help too.
Thanks,
Arnold
