1355501 - mozjs-38 segmentation fault when building with --with-intl-api (default configure option)

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

Description

[Guido Trentalancia]

Attachment: gnome-shell-debug-intl.txt

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/604.1 (KHTML, like Gecko) Version/11.0 Safari/604.1 Epiphany/3.24.1

Steps to reproduce:

- build mozjs version 38.2.1.rc0 with default configure option (equivalent to using --with-intl-api);
- start gnome-shell (e.g. from gnome-session);
- gnome-shell crashes after a few seconds (it happens every time).


Actual results:

gnome-shell (linked against libmozjs) crashes with segmentation fault in libmozjs.


Expected results:

gnome-shell should not have crashed due to a bug in the mozjs shared library.

It is possible to avoid the bug only by compiling mozjs with the --with-intl-api=build configure option.

The ICU library installed on the system is version 58.2 (--with-system-icu configure option is used).

The error is caused by http://bugs.icu-project.org/trac/ticket/12827. I think there are only two options to workaround this crash, you either need to disable Intl or use an ICU version which isn't affected by that bug.
