Bug 53680 – [GTK] fast/frames/sandboxed-iframe-scripting.html is flaky

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Philippe Normand]

Crashing sometimes on 64-bits Debug:

http://webkit-bots.igalia.com/amd64/svn_77474.core-when_1296735359-_-who_DumpRenderTree-_-why_11.trace.html

I can't locally reproduce this issue, but will skip the test.

[Philippe Normand]

Skipped in http://trac.webkit.org/changeset/77486

Note, this bug could be related with bug 53673. Both crashes are malloc errors

[Martin Robinson]

I'm pasting in the stack trace here and CCing relevant people. I think we should try to do this for all new bugs otherwise the stack link will break and no one will fix this.

This might be related to 53104 (https://bugs.webkit.org/show_bug.cgi?id=53104). Could you please check if this test is still flaky after 53104 is fixed?

[Martin Robinson]

Unskipped the test and closing this. Will re-open if the failures reappear.
