I will do some more testing to attempt to reproduce the issue. REGRESSION: I believe the regression point is at 267014@main, as this is the first crash instance and appears to have changes directly related to the subject of this test.

Test gardening commit 267062@main (8b5bc663a8ee): <https://commits.webkit.org/267062@main> Reviewed commits have been landed. Closing PR #16850 and removing active labels.
REPRODUCIBILITY: I was able to reproduce this bug on macOS Ventura on the WK2 debug build at 267085@main by running the following command: rwt --clobber-old-results --debug --test-list=/path/to/run_tests.txt --force --verbose ipc/restrictedendpoints/no-test-only-ipc-expected-crash.html ipc/restrictedendpoints/test-only-ipc-allowed.html This problem only reproduces when ipc/restrictedendpoints/no-test-only-ipc-expected-crash.html is run before the reported test.
CORRECTION: Command was: rwt --clobber-old-results --debug --force --verbose ipc/restrictedendpoints/no-test-only-ipc-expected-crash.html ipc/restrictedendpoints/test-only-ipc-allowed.html
