[v3] std::uninitialized_copy test

2012-04-17 Thread Benjamin De Kosnik

Found this bug in 4.4 branches, fixed with the following in later
branches:
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01616.html

But the test case is useful anyway.

Definitely, thanks! The name of the new testcase seems a bit weird (for 
the FSF branches): shall we maybe refer to the original (Fedora or RHEL 
Bugzilla, I suppose) PR in a comment and then use either an explicative 
name (our current practice) or just a small number for the name of the 
testcase itself?


Thanks again,
Paolo.

Yes, agreed. I couldn't think of anything descriptive for this test,
but if you can please feel free to assign it something meaningful.
