Hi Bradley:

I've just took my time to search more about this issue and i conclude
that actually it's not an eclipse bug, but rather the problem exists
in the way xulrunner is builded.

First, Eclipse's SWT Browser (it's internal web browser) uses
xulrunner depending in its version [1], so the current Eclipse 3.6.x
requires XULRunner 1.8.x - 1.9.2.x.

And second, SWT can use xulrunner *just* if this was builded without
it's optimization flag [2] and i have seen that Alien Bob's one [3]
(SBo also [4]) uses "--enable-optimize="$CFLAGS" \"

According with Grant Gayed it's really important to build xulrunner
without the use of "--enable-optimize" [5] to get a functional eclipse
browser (swt+xulrunner) both in x86 and x86_64. Also he makes another
important question, ¿which platform of jre (and i add jdk) you use? If
you use eclipse x86_64, then it would search for a jre/jdk x86_64 and
a xulrunner x86_64. Important to know to avoid issues between them

Actually i think that they know about this "bug", but its not in their
hands to decide how a linux distribution builds xulrunner.

I've already send an eclipse SlackBuild update for version 3.6.2 to
André Barboza (the current maintainer) but i have not the
time-platform to test if its true what Grant Gayed stated in his
posts. If someone can make some test in this aspect could be very
helpful to "fix" this situation. Just build xulrunner *without* the
use of "--enable-optimize" (or "--disable-optimize" if applies) and
let eclipse decides the use of uxlrunner *without* your meddling
[8][9][10]. And yes... i think that André Barboza solution (patch) its
not the correct answer but maybe i could be wrong ;-)
