There needn't be a resulting (i.e. output) file for this bug to
manifest.  The corruption is seen in the Perl program as the files are
being *read*, not written.  Likewise with the recurrence of the bug in
Araxis merge.

It seems, though I have not yet done a complete survey of a large enough
sample to be 100% certain, the files being read are all Variable length
record format, and not Stream or Stream-LF.

OK, so far this is consistent with our test results.  We'll let you know
if we discover corruption in other file types, e.g. Stream or Stream-LF
files.
