Status: RESOLVED DUPLICATE of bug 1340921

(Web Compatibility :: Tooling & Investigations, defect)

Description

[Adam Stevenson [:adamopenweb]]

Testing with Nightly 54.0a1 (2017-02-21) on OSX 10.11.6.

STR:
1. Launch Nightly 54.0
2. Ensure ipc.processCount is set > 1
3. Navigate to: https://www.just-eat.ca/restaurants-shanghai-chinese-food/menu
4. Click the Firefox menu then Report site issue

Expected Behavior:
New tab opens on webcompat.com, with screenshot of tab

Actual Behavior:
New tab opens, page starts to load, then browser crashes

I found that https://miketaylr.com/ also causes the crash.

Mozregression pointed to bug 1303113.

This was tested on a Macbook Pro (15-inch, Mid 2015 w/AMD Radeon R9 M370X).

When testing on an old iMac running OSX 10.9.5, I can't reproduce the crash on justeat.ca but I can on miketaylr.com. But if I change ipc.processCount to 1, there is no crash.

Adding the crash signature so this gets picked up in a query - this product doesn't seem to have a crash stats field: [@ <name omitted> | mozilla::dom::BlobParent::RecvPBlobStreamConstructor ]

Marking as a dupe of Bug 1340921 to make it easier to track - and there is also a needinfo in that bug.
