| Bug report for Octave 2.0.14.90 configured for i686-pc-linux-gnu
| 
| Description:
| -----------
| 
|   Calling quad two or more times in a row on the same function
|   causes it to return an "invalid recursive call" error. 
|  
| Repeat-By:
| ---------
| 
| The integrand function is f2.m (any seem to cause the error, but 
| I'll give you this sample)
| 
|       function ff = f2(x)
|       ff= sqrt(x*(1-x));
| 
| Here's the sequence of commands
| 
|       octave:1> quad('f2',0.001,0.999)
|       ans = 0.39266
|       octave:2> quad('f2',0.001,0.999)
|       error: quad: invalid recursive call
|       error: evaluating index expression near line 2, column 1

This problem should be fixed in the current release of Octave, version
2.0.16.
