Brad,
if your DLM routine has keywords, you should be calling IDL_KWFree just
before the routine returns. If you don't, unexpected things may happen, even
though the IDL API tries to be forgiving at time.

I cannot recall seeing that particular message... can you post a small
example of your C code that shows what you are doing? You can take a
look at the mechanisms I use for passing keywords in some of my DLMs
at:

Thanks, everyone, for the input. Of course, the answer to my question
'Why am I getting a IDL_KWFree() error when I'm not calling
IDLKWFree()?' is that I -should- be calling IDL_KW_FREE.

It turns out I had mistakenly copied in some code from the old API, and
was using IDL_KWCleanup instead..
