Regression in integration



Is this a known problem, or was it created by my askequal + new integration for x^n code?
The integral is divergent:

$ ./maxima-local
Maxima branch_5_30_base_87_gab7ecfd_dirty http://maxima.sourceforge.net
using Lisp Clozure Common Lisp Version 1.9-r15764  (WindowsX8632)

(%i1) integrate(1/sin(x),x,0,z);
Is z positive, negative or zero?

pos;
Is z positive, negative or zero?

pos;
Is z positive, negative or zero?

pos;

Then Maxima stops working...
