[netCDF #GNP-293876]: module file problem

Hi Again, Todd,

> *** testing attribute renaming for memory leak, like nc_test...FAIL: tst_atts
> ================================================
> 1 of 10 tests failed

That's the first time I've ever seen that test fail.

If it's convenient, could you edit the nc_test/tst_atts.c file to help
locate where the error is occurring?

What would be sufficient is replacing the "main" function starting at
line 2472 in that file with the appended version of "main" that has
more instrumentation to show what's happening.  Then run "make check"
in that directory and send us the output.

If you don't have time for this, an alternative would be to try the
new netCDF-4.2 release to see if you have any better luck with that.
However, the test program that's failing is no different in version
4.2, although there have been various bug fixes in the library.  For
details how to get it, see this announcement:

Thanks!
