The following program fails to raise an error condition in the deallocate
statement. The pointer target was not created by an allocate.
Dick Hendrickson
program MF0069
! fails on Windows XP
! gcc version 4.4.0 20080312 (experimental) [trunk revision 133139]
! F95 page 83, line 34 says deallocating a pointer whose target
!wasn't created by an ALLOCATE causes error condition
REAL, pointer :: RLA(:)
REAL, TARGET :: RLA1(6)
RLA1 = 0
RLA => RLA1
DEALLOCATE (RLA, STAT = ISTAT)
IF (ISTAT .LE. 0) print *, 'deallocate did not fail!', istat
END
