Apparently, this was #7557 all along. I uploaded a patch. Please review.

Numerical evaluation for this function is done by the _evalf_()
function defined on line 489 of sage/functions/special.py. The last
line of that function is:
return parent(maxima("%s, numer"%self._maxima_init_evaled_(*args)))
Here is what happens:
sage: maxima("jacobi_sn(1.2000 + 3.7081493546027438*I,
0.5), numer")
jacobi_sn(3.7081493546027438*I+1.2,0.5)
Trying to convert this to an element of RR, or whatever the chosen
parent for the numerical evaluation is, calls this function again.
The problem is with the conversion of the argument to maxima in the
_maxima_init_evaled_ function. I will open a ticket and try to provide
a patch today. Gotta run now.

With sage-5.0-beta2, the above is duplicated, except that the last line has
been going (and going, and ...) for several minutes now, with no signs of
abating. It's adding small increments of memory, second by second...
