Status: VERIFIED WORKSFORME

(Core :: JavaScript Engine, defect)

while working on the mochitests for windows mobile, I ran into an issue while getting the httpd.js server running from xpcshell.exe.  I have narrowed the problem I found down to this line of code:
http://mxr.mozilla.org/mozilla-central/source/testing/mochitest/server.js#151

If I replace __LOCATION__.parent with:
  var sb  = Components.classes["@mozilla.org/file/local;1"].
                     createInstance(Components.interfaces.nsILocalFile);
  sb.initWithPath("\\Tests\\mochitest\\test2.js");

  serverBasePath = sb.parent;


I can get it up and going.  Poking around in the code, I cannot figure out why we would have this issue (hence the bug).

This is tested on my HTC Touch Pro device with a build from last week.

Can we get a stack?

could be related to: https://bugzilla.mozilla.org/show_bug.cgi?id=470914#c14.

Working on a debug build to see if that will produce a stack.

ok, after looking into this further, it looked like a crash the way I was running it, but it turns out that we terminate the xpcshell script when we hit __LOCATION__:

It is my understanding that blassey has a patch for getcwd on wince.

if I use the --environ:"CWD=..." this works.
