Assuming you bumped the array dimensions, as a general rule
here is what one should do when hacking this sort of code:

% grep -i propf *.f

-- to find any other places where the common block might be

% grep <original dimension> *.f

-- to find any variables that are set to the array dimension,
since one of these is what will be used in checking for the max.

Ideally the code could be structured so that the array dimensions
would be automatically tied to that variable, e.g. via a
parameter statement in a sizes.h file.

All this is speculative in that I haven't looked at the code in
a number of years.
