Screen crashing when built for snps_arc32_defconfig

[jzbydniewski]

I'm using branch arc-2023.09, config snps_arc32_defconfig
I added screen and libxcrypt in menuconfig.

After running the vmlinux in nSIM, I can see the following crash when trying to run screen and typing some newlines there

# screen
[..] type here something line 15-20 newlines
#
[screen caught signal 11. (core dumped)]
#
#
#
# potentially unexpected fatal signal 6.
