Not set

With a seamonkey gtk2 build, pages do not get scrollbars even if the window is
too small.  I saw this with a build from 19:54 PDT and 18:32 PDT, but not 16:50
PDT indicating the checkin from 286000 caused this.

I could not reproduce the problem with a firefox gtk2 build from 23:11 PDT
Saw this on Seamonkey at the same time Andrew did.

Unlike Andrew, however, I am also seeing this on Firefox GTK2 build (checkout
started 23:15 PDT)
I saw this problem in a just-pulled Firefox build (1am PDT, 4/6/05) on WinXP SP2.

Valgrind is seeing this:

I added this:
           aParent->GetNodeInfo() &&
           aParent->GetNodeInfo()->Equals(nsSVGAtoms::use, kNameSpaceID_SVG))
        bindingParent = aParent;
       rv = content->BindToTree(aDocument, aParent, bindingParent, PR_TRUE);
+      fprintf (stdout, "rv=%d\n", rv);
       if (NS_FAILED(rv)) {
         return rv;

the first call returned rv = 5354252.  I added "rv=14;" before the call to
BindToTree, and it "works" now.  rv=0 always and I have scrollbars.  That smells
like a compiler bug, but that wouldn't explain someone seeing this on WinXP...

Attached patch Patch (untested) (obsolete) — Splinter Review
I presume only non-SVG builds are seeing this?

If MOZ_SVG is not defined, and any of the applicable if statements are true in
the MOZ_XUL and MOZ_XTF sections, then rv is never set since it effectively
falls into the else clause.

In the patch the additional |bindingParent = content;| effectively does
nothing, but that's the easiest way I can think of without using empty

Patch (untested)

Mook, nice catch!  And yes, all my builds were SVG builds....

This isn't quite the approach I think we should take here, though.  Different
patch coming up.

I think an empty block (with corresponding comment) is actually clearer here
(and lets me make the svg block like the others to prevent this from happening

r+sr+a=shaver for 1.1a checkin so that we work even without SVG.

Sorry, I meant 1.8b2, which I think eventually leads to 1.1a, but really...

Fixed on trunk.  Thanks for figuring out what the problem was, guys!  And my
apologies for the trouble.
Oh, and people might want to remove the blocking nominations from this bug....
