I am having serious problems getting nf90_inquire_variable to behave.  I
have now had issues with this library function 3 different times using 3
different compilers on 3 different Linux machines, with 3 different codes.

The first time I was using Intel ifort compiler.  This code gave me a
segmentation fault (core dump) error.  I was using
a previously written FORTRAN wrapper code which called this function.
 I sand-boxed the function and slowly rebuilt the code from the ground up
and this time I did not have the segmentation fault error.  Never did
figure out what caused the problem, but just re-writing the code exactly
the same way as before seemed to work.

The second time I was using Portland Group pgf90 compiler.  This code did
not give me a segmentation fault, it actually returned the a -36 error
code.  I was correctly passing it a dimids array, but once it got into the
library code it could see that the array existed but it saw it as size 0,
not size 4 (or NF90_MAX_VAR_DIMS - when I tried that instead).  I finally
got this to work by changing the nf90_inquire_variable function in where it
declares integer, dimension(:),optional, intent(out) :: dimids and changed
it to integer, dimension(nf90_max_var_dims),optional, intent(out) :: dimids.

Now the third and final time I'm attempting to use this function I am
compiling it with the GNU gfortran compiler.  It is once again giving me
Segmentation fault (core dump).  I tried re-writing the code again as I did
with the ifort code, but that did not work.  I also tried the fix I used
for the pgf90 compiler and that too failed to fix the problem.  I am now
totally stumped with this function.

Has anybody else experienced these types of issues?  If so how did you
solve it?

Thank you,
