I have built sysutils/screen (screen-4.7.0_4) on a wandboard-quad running: 
FreeBSD 13.0-CURRENT r352778 GENERIC  arm
The version of the ports tree is:
Last Changed Rev: 516289
Last Changed Date: 2019-11-02 07:24:29 +0000 (Sat, 02 Nov 2019)
The build (using ports-mgmt/poudriere-3.3.2_1) finished successfully.

If I start sysutils/screen: 

root at wqtest:~ # gdb /usr/local/bin/screen
GNU gdb (GDB) 8.3.1 [GDB v8.3.1 for FreeBSD]
...
Reading symbols from /usr/local/bin/screen...
(gdb) run
Starting program: /usr/local/bin/screen 
[Detaching after fork from child process 13723]

I get error messages in /var/log/messages:

Nov  3 15:22:04 wqtest SCREEN[13723]: stack overflow detected; terminated
Nov  3 15:22:05 wqtest kernel: pid 13723 (screen), jid 0, uid 0: exited on
