741231 - crash with emscripten generated code

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Morgan Borman]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Build ID: 2012021500

Steps to reproduce:

When I load "/test/js/main.html" (included in the attached zip file), the JavaScript library that I have compiled to JavaScript with emscripten https://github.com/kripken/emscripten causes Firefox to crash.

I am using firefox 10.0.2


Actual results:

Firefox crashes with no messages or errors except that the bug report tool pops up.


Expected results:

Firefox should load the file or at least tell me there was an error rather than crashing.

I can't reproduce a crash on FF10, 11 or 14 on 32-bit linux. Perhaps this is a 64-bit specific issue.

Upgraded to FF11.0 and crash still occurs on my system.

Also occurs with a fresh profile.

As I understand it, to reproduce one would have to:
1. unzip the attached file into a folder, then
2. make a HTTP server to serve the contents of the folder (e.g. with |python -m SimpleHTTPServer 8000|), and
3. open a URL like http://localhost:8000/test/js/main.html

This doesn't crash for me either on Mac Firefox 11 or the latest nightly. Do you use the build from mozilla.org? Could you submit a crash report and post the report URL here?

It can run fine from the local filesystem. No need to put it on a web server.

I'm using the build in the openSuse 12.1 repositories, but I'll get the official build and try that.

How does one acquire the URL from one of those crash report dialogs?

Er, OK. I thought the file:// pages couldn't access files from the parents dirs, but apparently for <script> it works fine.

Still trying to get the release ( or any other versions besides the ones from the repository) to actually run on my system. (problems with 64 OS I think) Once I do I'll get some data from them if the issue is still present there.

Doesn't seem to crash using 32 bit version from openSuse repository.

Comment 10

[Morgan Borman]

Nor with official 11.0 linux binaries.
