13.0-RC3 bison causes tputs SIGSEGV

I ran into a bit of an odd problem when building the
sysutils/grub2-bhyve port on 13.0-RC3 (on x64).  The bison command
dumps core when the output is going to a console.  Redirecting the
build output to a file avoids the problem.  I'm not sure if this is
an ncurses issue, a port issue (and which port?), my box, or
something else (clang?).

This is what the tail end of the port build looks like:
...
grub-mkfont: No (explicitly disabled)
grub-mount: No (explicitly disabled)
starfield theme: No (No grub-mkfont)
With libzfs support: Yes
