bug#47378: Emacs 27.1 binary Mac OS build crashes on Big Sur (11.x)

[Victor Tsaran]

Hi.

Just wanted to follow up here. Is there any more information I can provide?

I have seen an upgrade to the Mac build, however, this did not fix the issue.

Thanks a lot.

AFAICT, the only call to malloc in draw_glyphs is via SAFE_ALLOCA.
