I thought so too, but in this case it is a autoconf 2.57 output which is
failing, ending up with a lot of control characters instead of the
expected sed backreferences..

The package in question is the Squid-3 development snapshots found at

The failure is seen at least in the cppunit subpackage called
recursiverly from the main configure. Maybe in the main package as well.

My access to systems with a shell behaving like this is somewhat limited
so I have not produced a smaller test case for the problem. So far Linda
is the only one reporting this issue to us, but shells behaving like
this is not very wide spread in our community of Squid-3
snapshot/development release users..
