[xml/sgml-pkgs] Bug#587271: libxml2 zegfault reading any xml file on amd64

[Marc Chantreux]

Package: libxml2
Version: 2.6.32.dfsg-5+lenny1
Severity: grave
Justification: renders package unusable


hello dear maintainers,

since 2 days, every single xml file parsing segfault (with xmllint as
well as with perl XML::Simple).

- I tried to apt-get source and compile again: same pb. 
- using gdb and some code hacks, i saw the segfault appears at xmlIO.c:2412
  because cptr is out of bounds.
- collecting more infos is WIP.

regards
