Summary: sqrt~ giving only -inf/inf

Initial Comment:

For the G4 and Intel optimized builds of Pd-0.39.2-extended-test7 on Mac OS X, sqrt~ only returns -inf or inf.  (Does this affect other platforms?)  This is probably related to the auto-vectorization.  This is not a problem on Pd-0.39.2-extended-test7 that was built for G3s.

Check the sqrt~-help.pd file for a test patch.

sqrt~ of the signal 9 returns -\infty, hence not 3 as expected. All tried int signals greater then zero returns -\infty. To test this, see either the attached patch (which is very close to the help-patch for [sqrt~]) or the help-patch for [sqrt~].
