Summary: ASSERTION FAILED: arguments.isObject() in
JSC::sizeOfVarargs
Classification: Unclassified
Product: WebKit

Test case
Load this test with debug jsc:
Array.from.apply(encodeURI,Symbol(17725));
Note: the failure was experienced with an EFL jsc build but it does not seem like a port specific issue.
Backtrace:
