Description From 2018-09-16 11:33:41
Using fax2tiff from libtiff version 4.0.9 (or compiled from current master,
981e43ec) I observe the following behavior:

$ fax2tiff -4 -P -X 1728 -B -M -o out.tif in.raw
in.raw: Empty input file.

And out.tif is a 267-byte file which appears to be corrupt.  Using fax2tiff
from 4.0.8 or earlier, the command produces no output and a valid 18,977-byte
TIFF file.

I have bisected the regression to 1cb6c46b9db2c589f76bee6d760f96fa6bc0c835 (the
first bad commit).

The test file I used contains name and phone number information for a client,
so I would prefer not to post it publicly.  Let me know if it would be useful.

Thanks,
Kevin

Bugzilla is no longer used for tracking libtiff issues. Remaining open tickets,
such as this one, have been migrated to the libtiff GitLab instance at
https://gitlab.com/libtiff/libtiff/issues .

The migrated tickets have their summary prefixed with [BZ#XXXX] where XXXX is
the initial Bugzilla issue number.
