- Subject: 20060322: dcrdf problem
- Date: 22 Mar 2006 12:13:40 -0700
Scott/Steve,
I had a problem with dcrdf core dumping on Linux in the
bridge/rd/rddcpm.f routine. I didn't see this in your 5.9.2 release
notes on the web, so don't know if you have run in to this or not.
The problem is that the sorted insertion iteration on "nn" in the
section below can attempt to access an array index "0" when n=2
(eg (nn - 1) = 0):
ELSE
prmfnd = .false.
n = 1
DO WHILE ( .not. prmfnd .and. n .le. 3 )
IF ( iwxp (m,k) .gt. i3num (n) ) THEN
IF ( n .lt. 3 ) THEN
DO nn = 3, 3 - n, -1
i3num (nn) = i3num (nn - 1)
i3prm (nn) = i3prm (nn - 1)
END DO
END IF
i3num (n) = iwxp (m,k)
i3prm (n) = m
prmfnd = .true.
END IF
n = n + 1
END DO
I modified the loop to:
nn = 3
DO WHILE (nn .gt. n )
i3num (nn) = i3num (nn - 1)
i3prm (nn) = i3prm (nn - 1)
nn = nn - 1
END DO
I have attached the modified source file.
