#1894 limit(erf(sqrt(log(t))/sqrt(2)),t,0) -> Lisp error
This example gives a Lisp error:
(%i7) limit(erf(sqrt(log(t))/sqrt(2)),t,0);
Maxima encountered a Lisp error:
The value NIL is not of type FIXNUM.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
The constant sqrt(2) in the numerator or denominator is necessary to get the error. Without the constant the limit gives a noun form.
(%i8) limit(erf(sqrt(log(t))),t,0);
(%o8) 'limit(erf(sqrt(log(t))),t,0)
I think the source of the error is taylim (now the constant sqrt(2) is in the numerator):
(%i9) tlimit(erf(sqrt(log(t))*sqrt(2)),t,0);

I think this error has gone. We get a noun form for the examples of this bug report:
(%i4) limit(erf(sqrt(log(t))*sqrt(2)),t,0);
(%o4) 'limit(erf(sqrt(2)*sqrt(log(t))),t,0)
(%i5) limit(erf(sqrt(log(t))/sqrt(2)),t,0);
(%o5) 'limit(erf(sqrt(log(t))/sqrt(2)),t,0)
This might be due to the change of the code for simplifying 0^a which has been reverted in parts.
Setting the status to pending and the resolution to "works for me".
