Well it has taken a while
But I have finally foud the source of my Unhandled Exception Error from the __intel_alloc_bpv@4() routine
As Steve Lionel suggested, it is a Variable Format Expression causing the trouble.
Sample code is below - the write statement blows me out of the water.
So the question now becomes: What is the recommended solution or workaround?
K = kntTripPurposes(currentPeriod-1)
IF (K.gt.1) THEN
DO J = 1,PARKZONES
WRITE(45,"(F11.4)") (parksUsed(I,J),I = 1,K)
