1215090 - Try to land test case for bug 1186982

Status: NEW

(Core :: JavaScript Engine, enhancement, P3)

Description

[Lars T Hansen [:lth]]

This never landed successfully due to many OOM bugs, which may since have been fixed, we could try again (though decoder said on IRC that it's often hard to land these, they tend to fail sporadically, very annoying, if it continues to be a problem it can land in jit-test/manual-tests):
