[xml/sgml-pkgs] Bug#596013: libxml2: claims to be out of memory when validating SVG with XSD

[brian m. carlson]

Package: libxml2
Version: 2.7.7.dfsg-4
Severity: normal

I get an out of memory error from xmllint when validating an SVG file
(attached) with an XSD file[0].  The error occurs whether I use an http
URL or simply download the file to the local disk.

My kernel is set to the default settings with regard to memory, so it
should overcommit memory and never cause malloc to set errno to ENOMEM.
I also at this moment have over 675 MiB of free (not used for cache or
buffers) memory and have a total of 3 GiB total physical memory.
