New issue 4338 by [email protected]: Segfault when vector ICs are
enabled on ARMv6
https://code.google.com/p/v8/issues/detail?id=4338
Version: 4.4.63.25
OS: Raspbian
Architecture: ARM
The bug happens on io.js, on the branch that is trying to integrate latest
stable V8 4.4. It appeared somewhere between 4.4.63.19 (unaffected) and
4.4.63.25.
Current workaround is to use the --novector_ics flag on ARMv6.
What steps will reproduce the problem?
Build io.js from
https://github.com/targos/io.js/commit/4ec5c4422d59b6a8218de8c81d8fe9fdb7cc57a9
Run the following script:
var vm = require('vm');
var Debug = vm.runInDebugContext('Debug');
function breakpoint() {
debugger;
}
Debug.setListener(function(){console.log('debug event')});
console.log('before break');
breakpoint();
console.log('after break');
What is the expected output?
before break
debug event
after break
What do you see instead?
before break
debug event
after break
