First, this is definitely a CUPS upstream bug, so please report it on
the CUPS GitHub, also supplying all the information which you have
gathered and attaching the files which I had asked for.
https://github.com/apple/cups/issues/
Probably it can be solved by adding a simple NULL check.
At line 273 of rastertopwg.c replace
if (pwg_media)
strlcpy(outheader.cupsPageSizeName, pwg_media->pwg,
sizeof(outheader.cupsPageSizeName));
by
if (pwg_media && pwg_media->pwg)
strlcpy(outheader.cupsPageSizeName, pwg_media->pwg,
sizeof(outheader.cupsPageSizeName));
Please try it if you are familiar with source code and compiling. Tell
your result here and also in the upstream bug you are reporting.
