----------------------------+-------------------------
I have two spatial-temporal datasets: `tp2` and `tp5`. `t.rast.mapcalc`
works when using one dataset:

{{{
t.rast.mapcalc in=tp5 exp="tp5 < 40" out=water basename=water --o
}}}

But combination of two datasets fails:

{{{
t.rast.mapcalc in=tp2,tp5 exp="tp5 < 40 || tp2 < 40" out=water
basename=water --o
}}}

with

{{{
