[AppleWin][DumpRenderTree] flaky crashes in computeSHA1HashStringForBitmapContext

I'm observing flaky crashes in computeSHA1HashStringForBitmapContext on AppleWin EWS.
For example,
attachment 417626 [details]
https://ews-build.webkit.org/#/builders/10/builds/72196

The following three tests crashed:
  mathml/presentation/semantics-2.html
  svg/animations/animate-marker-orienttype-4.html
  svg/as-background-image/svg-transformed-background.html

Callstack:
