[Simon Fraser (smfr)]

Various layout tests are asserting in LayoutTestController::pathToLocalResource() on the SL leaks bot:

There is clearly a bug here:

http://trac.webkit.org/changeset/95588/trunk/Tools/DumpRenderTree/mac/LayoutTestControllerMac.mm
414	    // Note: It's important that we keep the file:// or http tests will get confused. 
415	    if (localResourceString.find("file://") != std::string::npos) { 
416	        ASSERT(absolutePathToLocalResource[0] == '/'); 

It should read:

415	    if (localResourceString.find("file://") == std::string::npos) { 
416	        ASSERT(absolutePathToLocalResource[0] == '/');

Did this just start?  This change was landed long ago, no?

Oh wait, this is not it. I misread the code.

I think this has always failed. It appears that it's coming from webkit port difference. I can reproduce the crash if I run:
 Tools/Scripts/run-webkit-tests --debug --leaks fast/loader/local-JavaScript-from-local.html

but can't reproduce the crash if I run:
 Tools/Scripts/run-webkit-tests --debug fast/loader/local-JavaScript-from-local.html

I am able to reproduce the failure.  Not yet sure what's causing it. :)

Ah.  Looks like --leaks is using ORWT.  I thought it was using NRWT.  I'll make the change to ORWT.

No wonder!
