[libxml-devel] [patch] Fix GC-related segfault on amd64 (libxml-ruby 0.3.8.4)

[Masashi Shimbo]

Hi,

Attached is a patch (against libxml-ruby 0.3.8.4) that should fix
segmentation faults in XML::Document.file.

The patch hasn't been tested much, but the problem described in

http://rubyforge.org/tracker/index.php?func=detail&aid=8337&group_id=494&atid=1971

(originally reported for freebsd-amd64) goes away on my Ubuntu Linux
6.10 amd64 box (with ruby 1.8.4 / gcc 4.1.2).

Alternatively, it is possible to avoid the problem by turning off the
compiler optimization altogether (by providing gcc with -O0), even without
the patch.
