Details:

Hello,

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

The stack traces are as follow:
```st
==30014==ERROR: AddressSanitizer: stack-overflow on address 0x7ffe3b2a6fc8 (pc
0x7f32ffcb6d2e bp 0x7ffe3b2a7060 sp 0x7ffe3b2a6fd0 T0)

    #11 0x7f32ffa10df1 in parse_inverting_unary_operator
src/language/expressions/parse.c:606
```
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 build it using `make -j10`, and run it with:

```
./pspp <attached file> format= -I- -O -V format=odt -r device=treminal
device=listing /dev/null --no-output -o -h
```
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.
