Crash exporting to GS7BG format

[marisn]

• Search through existing issue reports and gis.stackexchange.com to check whether the issue already exists
• Test with a clean new user profile.
• Create a light and self-contained sample dataset and project file which demonstrates the issue

Describe the bug
Saving to GS7BG causes a segfault. The same dataset can be converted with gdal_translate without any problems.

How to Reproduce
Open any raster dataset and go to export. Choose "Golden Software 7 Binary Grid", enter file name and click save. Segfault in a few seconds.

QGIS and OS versions
Tested with 3.8.1 on Gentoo ~AMD64 with gdal 2.4.1
Originally I got a notice from a Windows user running 3.8.2.
