segfault with v3.1.0 and possibly --harmony-arrow-functions #2561
Description
Activity
Can you produce a minimal, reproducible example? What platform is this on?
I just tried a simple script (with
--harmony-arrow-functions) that used fat arrows on v3.1.0 on Linux and did not encounter this issue.It seems to work fine here as well with a smaller sample,
So I guess it's not directly related to--harmony-arrow-functionsThe following script works fine on 3.2.0 :
'use strict' let callback = (name) => { console.log("hello " + name) } callback("shai")
But specifically when running my server (which works fine on 2.5.0 as well as 3.0.0) , it crashes with a Segfault.
Is there any way to get more verbose output so I can give a better direction for this?
Thank you
What OS is that? Try running it through either
gdborlldb, for examplelldb -- iojs file.jsand thenrand probablybt.Not sure if related, but found an issue where
0.12.xgives anECONNREFUSEDerror,3.2.0segfaults. Can create a separate issue if not related.img

@yoshuawuyts can you open a new issue?
Also, can both of you use either lldb or gdb, or mdb to get a thorough breakdown of what is happening in the segfault? Feel free to ask if you need more info, setting this stuff up isn't particularly trivial.

[-]Super odd Issue - 23267 segmentation fault[/-][+]segfault with v3.1.0 and possibly --harmony-arrow-functions[/+]on Aug 31, 2015 @Fishrock123 I'm willing to run that, but could you point me in the right direction on how to set that up? Thanks!
Been a while since I did it. @thlorenz has a guide here for lldb on OS X: https://gist.github.com/thlorenz/30bf0a3f67b1d97b2945 (Not sure if it is up-to-date, when I did it I didn't patch lldb and it worked?)
@freak4pc Could you let us know what OS you're seeing this on at least? :)
Sorry guys, I'm pretty much flooded with work now.
I'll try to get more info from lldb tomorrow and post it here...is this still an issue in the latest stable (v4.2.1 as of now)?
Closing due to inactivity and the fact that arrow functions are no longer behind a flag as of v4. If this is still an issue please feel to reopen. Thanks!
When trying to run the following
iojs --harmony-arrow-functions dreamdate.jsThis issue isn't happening in io.js v2.5.0 , and also doesn't happen on io.js v3.0.
Starts from v3.1.0.
