This would be shocking in the GPU Process - but it seems like incorrect WTF symbolication, as the actual crash log is more reasonable:

0   com.apple.JavaScriptCore      	0x0000000142471fd4 WTFCrash + 20 (Assertions.cpp:328)
1   com.apple.WebCore             	0x000000011c443d20 WTFCrashWithInfo(int, char const*, char const*, int) + 32 (Assertions.h:754)

Still, no good.

4X http/tests/media/modern-media-controls/time-control (layout-tests) are very flakily crashing on macOS ToT. I'm not able to update the title.

These all appear to share the same/very similar crash stdio output:

I'm able to reproduce this crash on macOS ToT running 1k iterations of command:

run-webkit-tests -f --force http/tests/media/modern-media-controls/time-control/10-hours-or-more.html
