That was r42659, which generates an error if you use both expression=
and file=. It's unrelated to the GDAL issues (which are in lib/raster
rather than r.mapcalc per se).

The error indicates that you have have enabled output via GDAL
(r.external.out). Use "r.external.out -r" to revert to native output,
or use "r.external.out -p" to check your settings.

If you want TIFF output, you should probably set the extension to
".tif" or ".tiff" ("r.external.out ... extension=.tif").
