Debugger Problems
-----------------

   There are some known problems when using `gdb' on code compiled by
`g77'.  Inadequate investigation as of the release of 0.5.16 results in
not knowing which products are the culprit, but `gdb-4.14' definitely
crashes when, for example, an attempt is made to print the contents of
a `COMPLEX(KIND=2)' dummy array, on at least some GNU/Linux machines,
plus some others.  Attempts to access assumed-size arrays are also
known to crash recent versions of `gdb'.  (`gdb''s Fortran support was
done for a different compiler and isn't properly compatible with `g77'.)
