This isn't related to string templates because this also fails: log('Content-Length: ' + xhr.getResponseHeader('Content-Length')); 1338834 1 ap 2017-08-15 13:27:33 -0700 Is this the same as bug 175590? 1338839 2 jfbastien 2017-08-15 13:31:03 -0700 (In reply to Alexey Proskuryakov from comment #1) > Is this the same as bug 175590? No, it's one of a few failures encountered in the wake of #175579. 1338881 3 ap 2017-08-15 14:30:50 -0700 Bug 175590 is about run-webkit-tests failing when test output contains a line starting with "Content-Length". This bug sounds like exactly the same thing - just a slightly different symptom when the value of the fake header us different. 1338898 4 jfbastien 2017-08-15 15:27:35 -0700 (In reply to Alexey Proskuryakov from comment #3) > Bug 175590 is about run-webkit-tests failing when test output contains a > line starting with "Content-Length".

When Dan and I debugged it we thought they were different issues. 1338932 5 dbates 2017-08-15 16:08:02 -0700 I know that this bug was filed one bug before bug #175590. I'm going to forward dup this to bug #175590 as bug #175590 provides detailed reproduction steps and has a reduced test case. *** This bug has been marked as a duplicate of bug 175590 ***
