#325: memory error using vectorize
------------------------+---------------------------------------------------
 Reporter:  stefan      |       Owner:  somebody   
     Type:  defect      |      Status:  new        
 Priority:  normal      |   Milestone:  1.0 Release
Component:  numpy.core  |     Version:  devel      
 Severity:  normal      |    Keywords:             
------------------------+---------------------------------------------------
 The following code causes python (and valgrind!) to segfault:

 {{{
 from numpy import vectorize, zeros

 vt = vectorize(lambda *args: args)
 # Removing either of the following lines cures the segfault
 vt(zeros((1,2,1)), zeros((2,1,1)), zeros((1,1,2)))
 vt(zeros((1,2,1)), zeros((2,1,1)), zeros((1,1,2)), zeros((2,2)))
 }}}

 with gdb pronouncing

 {{{
