bug #10574: Strange failure when using pinterp

Submitter:  Martin Rubey <kratt6>

Category:  interpreter Severity:  3 - Normal
Item Group:  code bug Status:  None
Privacy:  Public Assigned to:  None
Originator Name:  Open/Closed:  Open
Release:  Reproducibility:  None
Fixed Release: 
Error message: 

 Cannot convert from type Float to Polynomial Integer for value
   4.5

Example of code trigerring the bug: 

y x == (1+x)^x/x
interpolate(x,[1,2,3],[1/y(i) for i in 1..3])$PINTERP(x,FRAC POLY INT)

Internal cause:

Note that the failure only happens when issueing interpolate, but in this case, also thereafter, i.e., if you ask for y(2) afterwards!
