ifcodegen gets SIGKILLed on macOS if installed with QtMultimedia

QtAA requires both Qt Interface Framework and Qt Multimedia, so installing these is part of the standard procedure. Something goes wrong if either:

• these two are installed together
• Qt Multimedia is already installed before Qt Interface Framework installation

Steps:

Install Qt 6.7.1: Desktop, Qt Interface Framework and Qt Multimedia

Expectation:

ifcodegen works

Reality:

ifcodegen crashes

~/Qt> ~/Qt/6.7.1/macos/libexec/ifcodegen
fish: Job 1, '~/Qt/6.7.1/macos/libexec/ifcode…' terminated by signal SIGKILL (Forced quit)

This is a regression from Qt 6.7.0.

Any ideas for debugging? Originally I ignored this because the macOS full installation isn't working on 6.7.1 at the moment, but this might be a separate issue.
