Hi Ikumi

Many thanks - your suggestion to use the customize option to add
--max-print-line=1000 to the pdflatex command line works at least for the
current test case.
Adding -max-print-line=1000 - one hyphen rather than two - also works.
Perhaps auctex should be changed to add this as standard, since  bug#27088
suggests it could occur in various contexts?

Resulting output:
