failed to allocate string buffer exceeds maximum length on a book project when embedding resources

Originally posted by @prs513rosewood in #2462

Sorry to comment on a closed issue (EDIT: #2462), but I'm also encountering this problem. On my machine I had to increase the heap limit past the 8192 default introduced in recent quarto versions. However I also run a quarto render on a gitlab.com runner and the job gets killed, likely because of a memory overrun. Increasing the heap limit does not help there (this used to build successfully six months ago with quarto 1.3.450).

The repository in question is https://gitlab.com/prs513rosewood/projets-numeriques-discrets, here are the steps to reproduce:

git clone https://gitlab.com/prs513rosewood/projets-numeriques-discrets.git
cd projets-numeriques-discrets/
python3 -m venv venv && source venv/bin/activate && pip install -r requirements.txt
quarto render book
# I run with the execute flag, but the error is the same

Here's the output of quarto check:

Thanks for looking at this, the issue is preventing me from updating my class material.

Reproduce with quarto render book in the linked projets-numeriques-discrets repository, then inspect quarto.js around websiteOutputFiles and bookPostRender, where the stack trace reports the failure. Compare the failing book/_book/lj_tp.html path with the preceding render output. Done means the book renders without the string-buffer or out-of-memory failure.
