ignore my previous note. i was looking at evalframe, not
errframe. 

instead substitute the following bug: 

  When the PDL overflow handler runs, it doesn't set up an errframe.
  Why is this? Does it conserve so much stack space that it's not
  worth it? I wish ERRSET would trap PDL-OVERFLOW and I wish that 
  an ERRFRAME would exist when the PDL-OVERFLOW handler is called.
