With recent LaTeX, some documents trigger a TeX error message in the log which should be ignored, but currently is not causing automation from C-cC-a to fail.
The log file will for example contain ``` ./zut.tex:55: ignored error: Infinite glue shrinkage found in box being split ``` To trigger this, make sure your LaTeX is relatively current and fetch the minimal example from https://github.com/latex3/latex2e/issues/1907 (no need for `\RequirePackage{latexbug}` line). Then try C-cC-a from the Emacs AUCTeX buffer. The PDF will fail to show because Emacs will prompt the user thinking erroneously some real-life build error happened. Note that the `pdflatex` return status is `0`, which means that tools such as Latexmk do work properly. _______________________________________________ bug-auctex mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-auctex
