Hi,

Here's a small program that demonstrates an access violation bug in FTN95 5.10.0 and the work-around:

IMPLICIT DOUBLE PRECISION (A-H,O-Z)

! DOUBLE PRECISION EXPCHK ! OK if this is used
EXPFUN(T,N)=EXPCHK(T)/N
GLTFUN(T)=EXPFUN(T,3)

PRINT *, GLTFUN(22.2D0)
END

! Compiling this on FTN95 5.10.0 with:
!
! ftn95 /NO_BANNER /132 /ALT_KINDS /COLOUR /ERROR_NUMBERS /NO_OBSOLETE /OLD_ARRAYS /P6 /SAVE /CHECKMATE /FULL_DEBUG
!
! gives Access Violation: The instruction at 00509a25 attempted to read from location 0000000c
