Comment 1 for bug 1946727

I'm also seeing something similar. After a `cdo sinfo xxx.nc` I get:

```
...
cdo sinfo: Processed 1 variable over 7152 timesteps [0.06s 55MB].
free(): invalid pointer
Aborted (core dumped)
```

In fact, I get the error even if I just call `cdo` without any parameters

```
$ cdo
(... clipped output ...)
output file <0, 64, 96>; Default is 64
