Details:
Hello,
We are currently working on fuzz testing feature, and we found a **SEGV** on
`pspp`.
The stack traces are as follow:
```st
==29432==ERROR: AddressSanitizer: SEGV on unknown address 0x00000000023e (pc
0x7f0927fda525 bp 0x7ffc302e4dd0 sp 0x7ffc302e4d80 T0)
==29432==The signal is caused by a WRITE memory access.
==29432==Hint: address points to the zero page.

#7 0x556437d8ce30 in main src/ui/terminal/main.c:136
```
The full stack trace is attached.
**Step to reproduce**
We configured `pspp` using `CFLAGS="-g -O0 -fsanitize=address" CXXFLAGS="-g
-O0 -fsanitize=address" ./configure --prefix=$(pwd)/ --without-cairo
--without-perl-module` and built in using `make -j10`, and run it with:
```
./pspp <attached file> -e -V -I- -I -a --no-output device=treminal format=
```
The input file is attached.
**Environment**
- OS: Ubuntu 18.04.5 LTS
- GCC version: gcc 7.5.0
- pspp version: [pspp
1.4.1](http://mirror.yongbok.net/gnu/pspp/pspp-1.4.1.tar.gz)
Thank you.
