emacs-app: error invoking gcc driver

[Richard Cobbe]

I recently upgraded one of my machines to Sequoia 15.0 (there's an update pending to 15.1.1 that I haven't yet installed) and am in the process of reinstalling macports.  (I originally tried 'macports migrate' but I ran into the Apple CLI installer bug preventing a lot of C++ compilation and deleted my previous macports installation before I discovered the fix for that.)

I just reinstalled emacs-app @29.4_2+nativecomp+rsvg+treesitter.  It built correctly, and the resulting executable starts, but after a brief time, the *Warnings* buffer pops up, and it's full of a bunch of messages like the following:

⛔ Warning (comp): libgccjit.so: error: error invoking gcc driver
⛔ Warning (comp): /Users/r.cobbe/.emacs.d/elpa/auctex-14.0.8/tex-site.el: Error: Internal native compiler error failed to compile
⛔ Warning (comp): libgccjit.so: error: error invoking gcc driver
⛔ Warning (comp): /Users/r.cobbe/.emacs.d/elpa/auctex-14.0.8/texmathp.el: Error: Internal native compiler error failed to compile

Has anyone seen this?  Is there a workaround, or should I file a bug?  Rebuild without the nativecomp variant?

MacOS 15.0, Apple M2 chip.

Thanks,

Richard
