Surprising that https://github.com/WebKit/WebKit/pull/36471 doesn't seem to have caught this.

Looking at the content of TestWTF.WTF.CStringUninitializedConstructor, seems like this line: ASSERT_EQ(buffer[0], 0); Should indeed cause a crash, if I understand how `std::span` works.

The iOS API test bot didn't complete its final confirming test run before the PR was merged, and the crash only appears to manifest on macOS Sonoma+ (api-mac is running Ventura).
