Affects groff 1.22.4.


$ cat peng.ms 
.LP
Here is a picture of a penguin.
.PDFPIC unwritable/penguin.pdf
$ ls -dl unwritable
dr-x------ 2 branden branden 4096 Apr 26 05:42 unwritable
$ ls unwritable/
penguin.pdf
$ groff -U -ms peng.ms >| peng.ps
I/O Error: Couldn't open PostScript file 'unwritable/penguin.eps'
troff: peng.ms:3: can't open 'unwritable/penguin.eps': No such file or
directory


Switching to the 'pdf' device...


$ groff -U -ms -Tpdf peng.ms >| peng.pdf
$ echo $?
0


This is because a temporary directory was correctly used for construction of
the file that was sourced to read the image dimensions.  See bug #64061 for
more on that process than you ever wanted to know.

The program anonymously complaining of an I/O error would appear to be pdf2ps.
 From poppler-utils--try to contain your surprise.
