Details:


interp2(1:2, 2:-1:1, randn(2,2), (1:0.5:2)', 2:-0.5:1, 'pchip')


causes a crash in my current octave-dev:

 ***MESSAGE FROM ROUTINE DPCHIM IN LIBRARY SLATEC.
 ***POTENTIALLY RECOVERABLE ERROR, PROG ABORTED, TRACEBACK REQUESTED
 *  X-ARRAY NOT STRICTLY INCREASING
 *  ERROR NUMBER = -3
 *   
 ***END OF MESSAGE
 
 ***JOB ABORT DUE TO UNRECOVERED ERROR.
0          ERROR MESSAGE SUMMARY
 LIBRARY    SUBROUTINE MESSAGE START             NERR     LEVEL     COUNT
 SLATEC     DPCHIM     X-ARRAY NOT STRICTLY        -3         1         1

Segmentation fault (core dumped)


It happens each time one of the arguments is decreasing (consistent with the
interp2 help which only requires them to be monotonic).
