Thanks very much!

and ran this test:
(Smalltalk classNamed: #SHA256WithSHA2PluginTest) run: #testInputs
Linux64x64 had no crashes, but a few expected failures.
Linux64ARMv8 had no crashes but some unexpected test failures
Linux32ArmV6 had no crashes but some unexpected test failures.
So thanks, this bug seems squashed.
