There are some:
1. Gets confused when stepping over statements with MAX and MIN intrinsics.
Try stepping over the following code:
VAL1 = 0.49
VAL2 = 0.5
YMAX = AMAX1(VAL1,VAL2)
YMIN = AMIN1(VAL1,VAL2)
YMAX will get 0.49, and YMIN will be 0.50 (i.e., switched).
Works fine when not single-stepped.
2. Doesn't know the dimensions of array dummy parameters with variable
dimensions. i.e.
SUBROUTINE FOO(X,N)
REAL X(N,N)
Debugger will not be able to display elements of X properly.
