We are currently working on fuzz testing feature, and we found a **SIGABRT**
on `pspp`.

The stack traces are as follow:

Here is the full stack trace : [link]()

**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 build it using `make -j10`, and run it with:

./pspp <attached file> -O device=listing -o -a -e format=odt -O -o

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

Thank you.
