A problem with "vc" I ran into (with a core dump) is that blank fields
aren't being initialized to zero. When they are used in calculations, wierd
results occur, or a "Floating Exception, core dumped" occurs, killing your
data. I use blank fields in forms to indicate that data should be entered
there (and not where the 0.00's appear).
The fix is simple. Where "malloc" is called to allocate a struc, change
this to "calloc(1, *)", where "*" is the original malloc argument. This
will guarantee that the floating point data is zeroed. The sources to be
changed are interp.c, prog.c, and sc.c.
I am not posting a diff, because I have applied all the patches so far, and
the diff I could generate would contain much more than just my fix.
I would recommend that the author of "vc" post a new version, as I had a very
hard time applying all the current patches (some of them overlap).
regards,
joe
