<rdar://problem/106775188>
I was able to reproduce this crash at Ventura ToT as follows: run-api-tests --no-build TestWGSL.WGSLASTDumperTests.dumpTriangleVert --debug --verbose I was able to verify regression by running this test at 261690@main with the test crashing. This crash was not reproduced on 261689@main or 261686@main or prior.
The culprit was reverted in https://commits.webkit.org/261722@main
