Can you provide the exact message?

There shouldn't be any practial limitation on the length of an
expression in r60662 and later.

[Previously, there may have been OS-imposed limitations on the length
of a command line, but r60662 changed grass.script.mapcalc() to pass
the expression via stdin rather than the command line.]
