[Rd] .Fortran successful, R locks up.

I am having a problem with a library compiled from some legacy fortran
code. I can call the library, it runs as it should, returns a list,
and gives a ">" prompt, but then locks up the R session. Functions
typed in return nothing. ctrl-c results in a new prompt that is still
locked up, and R overwhelms the processor. This happens on Mac,
Windows, and Linux exactly the same. I close all open files and
confirm nothing is still open with unix lsof. I also have added a
routine to deallocate all allocated variables.
Does anyone have any suggestions in how I might be able to debug this
further? I have included output from the R session, top -o CPU, and R
CMD INSTALL below.
Thanks for your time on my behalf!
