We are currently working on fuzz testing feature, and we found a
**heap-buffer-overflow** on `pspp`.

The stack traces are as follow:
==29389==ERROR: AddressSanitizer: heap-buffer-overflow on address

    #9 0x55895cc19e30 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 -o /dev/null -O format=odt <attached file>
The input file is attached.

- OS: Ubuntu 18.04.5 LTS
- GCC version: gcc 7.5.0
- pspp version: [pspp

Thank you.
