Comment:

 This bug was not fixed in t.rast.mapcalc. A similar bug was fixed in
 t.rast.extract.

 However, fixing the bug in t.rast.mapcalc is more difficult since it uses
 a simple search and replace approach to substitute the input STRDS with
 map names and is not aware of what a space time dataset is. If the names
 of input and output space time datasets are include each other, then the
 module does not work properly. Choosing a specific order of the input
 STRDS in the input parameter (i.e: input=ndvi_smooth,QA_mask,ndvi) may
 reduce the risk of wrong substitution.

 However, please use t.rast.algebra instead. This module has other issues
 but is able to correctly identify space time datasets.
