[buildd-tools-devel] Bug#763896: schroot: infinite allocation on uid/gid entry errors.

[Daniel Serpell]

Package: schroot
Version: 1.6.10-1+b1
Severity: important
Tags: upstream patch

Hi!

The attached patch fixes an infinite allocation loop inside the
passwd::query_name, passwd::query_uid, group::query_gid and
group::query_name functions.

Current code simply fails with std::bad_alloc on any error,
because it always retries with a bigger buffer.
