Summary: integrate(atan(y),y,x,inf) loops endlessly

Initial Comment:

Maxima does not finish the calculation of the integral. After a (very) long time Maxima gets a stack overflow.

(%i1) integrate(atan(y),y,x,inf);

*** - Program stack overflow. RESET

[/build/buildd/clisp-2.44.1/src/eval.d:527] reset() found no driver frame (sp=0xbfea6430-0xbfea0200)
Exiting on signal 6
Aborted

I think the integral should be divergent.
