Subject: [PATCH] Bug 707264: Fix tiffsep(1) requirement for seekable output
|
|
files
|
|
|
|
In the device initialization redesign, tiffsep and tiffsep1 lost the requirement
|
|
for the output files to be seekable.
|
|
|
|
Fixing that highlighted a problem with the error handling in
|
|
gdev_prn_open_printer_seekable() where closing the erroring file would leave a
|
|
dangling pointer, and lead to a crash.
