Getting RunTime Check failure - variable 'R; used without being defined

[ferrad]

I'm geting the following error:

Run-Time Check Failure #3 - The variable 'R' is being used without being defined.

The trouble is I don't have any variables called R, not in the routine it breaks in, nor anywhere else (well I have a real, parameter :: R = 8314.4in one of the includes, but I'm sure it wouldn't complain with that?). I want to check for use of undefined variables, however this isn't helping me.

Any idea what's going on?

There is a bug in this feature, introduced some time after the initial 9.0 release, that causes the name of the variable in the message to be wrong nearly all the time. The fix for this is complicated but is in the works.

All I can suggest for now is to look at which variables are referenced at the point the error occurs.

Unfortunately it's on a return statement :(

Perhaps the function value was never defined?

Yes, spot on. :)
