[GRASS-dev] Limit in number of "variables" for r.mapcalc?

[Nikos Alexandris]

Hi devs,

is there a limit in the number of "variables" that r.mapcalc accepts
within from 'eval'? If yes, how big is it?

I am trying to feed r.mapcalc's eval with a fairly large number of pixel
modifiers and, given that the final expression is a valid one, the
execution ends with:

    debug=1 ended with error
    Process ended with non-zero return code -11. See errors in the (error)
    output.

Thank you, Nikos
