Subject: bug#37719: Recent ghostscript broke preview-latex again
Date: Mon, 14 Oct 2019 03:15:16 +0900

[Message part 1 (text/plain, inline)]

Dear Ghostscript developers,

Thank you for your continuing work on developing gs.  Unfortunately, I
have to inform you that recent gs source became not compatible with
preview-latex again:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=37719

I tried both gs 9.28 RC4 and fresh checkout of git repository of
ghostpdl.  I installed each of them with
env MAKE=gmake ./configure --prefix=$HOME/gs
gmake
gmake install
and set up the relavant path for this temporal installation, on FreeBSD
12.0 living in vmware on windows 10 home edition.  Then the invocation
of gs failed with a message quoted at the last of this message.

At the time of previous correspondence between us in this July,
preview-latex did work with gs 9.27 with patches suggested in
https://ghostscript.com/pipermail/gs-devel/2019-July/010161.html
applied, but it no longer does.  (By the way, the LaTeX developer
released new LaTeX this October, so the internal of the PDF file
produced by pdflatex might have some subtle difference from July.  I
attach the current PDF for reference.)

Could you please take a look and try to find a way to recover
preview-latex functionality?

Best regards,
Ikumi Keita
