1407977 - Crash with lots of failed "@mozilla.org/network/cache-service;1" instance

Status: NEW

(Core :: XPCOM, defect)

Description

[Oriol Brufau [:Oriol]]

Open browser console and enter this code:

  for (let i=0; i<1500; ++i) {
    try { Cc["@mozilla.org/network/cache-service;1"].createInstance(Ci.nsIXMLHttpRequest); } catch(err){ }
  }

Firefox crashes.

I have some crash reports in about:crashes, but they are not submitted when clicked. So I don't know the crash signature.

Seems a Windows problem, on Linux I only get "too much recursion".

Comment 2

nsIXMLHttpRequest was removed in bug 792808, so use something else like

  for (let i=0; i<1500; ++i) {
    try { Cc["@mozilla.org/network/cache-service;1"].createInstance(Ci.nsIDOMBlob); } catch(err){ }
  }

The crash report says it's an EXCEPTION_STACK_OVERFLOW
