Hello,
I'm having a problem while generating equations (and float) previews for the attached minimal working example, bug_report.tex. The problem seems to be related to the package "algorithm". When the file is opened into a buffer in Emacs, the AUCTeX menu becomes available. I try to generate the previews from the menu, selecting Preview -> Generate previews - for buffer. However, the generation of the previews stops at line 130 , where the \begin{algorithm}[H] command is. A file with the error output, bug_log.txt, is attached. The generation of the previews completes successfully when the lines 130 to 140, the full instance of use of the algorithm environment, are commented out.
When the .tex file is "compiled" with PdfLatex no errors are issued. I'm using AUCTeX 13.1.4 and TeXLive [pdfTeX 3.141592653-2.6-1.40.24 (TeX Live 2022)] on Windows 10.
A workaround for this problem, which I will try, is to use an alternative to the package algorithm, like algorithm2e. However, I thought it would be of interest for you to know about this problem and to warn the community of AUCTeX users about it.
Thanks,
Alejandro Garzon.
