Bug 126588 – js/script-tests/function-apply-many-args.js fails on ARM

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Michael Saboff]

It appears that the native C stack is too small top properly run function-apply-many-args.js.  When run on ARM64 with a ~1M stack, the output is:

Tests that we throw an error when passing a number of arguments beyond a certain threshold.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


PASS f.apply(null) is 0
PASS f.apply(null, []) is 0
PASS f.apply(null, [1]) is 1
PASS f.apply(null, new Array(10)) is 10
PASS f.apply(null, new Array(1000)) is 1000
PASS f.apply(null, new Array(65536)) is 65536
PASS f.apply(null, new Array(65537)) threw exception RangeError: Maximum call stack size exceeded..
PASS f.apply(null, new Array(65537)) threw exception RangeError: Maximum call stack size exceeded..
PASS f.apply(null, bigArray) threw exception RangeError: Maximum call stack size exceeded..
