--- Comment #3 from Darren Tucker <dtucker at dtucker.net> ---
What platform, compiler is this, and in particular what configure
options and CFLAGS did you give?  I see at least one non-standard
compiler flag.

A quick test with openssh-8.2p1 and openssl-1.1.1d here compiles OK:

$ CFLAGS="-g -O0 -D_FORTIFY_SOURCE=2 -DDEBUG_KEXECDH" ./configure
--with-ssl-dir=/opt/openssl/1.1.1d && make clean && make
[...]
$ ./ssh -V
OpenSSH_8.2p1, OpenSSL 1.1.1d  10 Sep 2019

$ ./configure --with-ssl-dir=/opt/openssl/1.1.1d
--with-cflags=-DDEBUG_KEXECDH && make clean && make
[...]
$./ssh -V 
OpenSSH_8.2p1, OpenSSL 1.1.1d  10 Sep 2019

(I also renamed my system openssl include dir, which didn't make a
difference).  Is it possible it's picking up includes from a different
version of OpenSSL somewhere in the search path?

wait, OpenSSH 8.2p1 doesn't even contain that line of code.

$ curl -s

| grep num_write

what modifications have you made to the code?
