Subject: Re: libstdc++/10505: concepts checks fail if container of X is used as member variable of X
Date: Mon, 05 May 2003 14:43:00 -0000	[thread overview]
Message-ID: <20030505144340.27792.qmail@sources.redhat.com> (raw)

Synopsis: concepts checks fail if container of X is used as member variable of X

State-Changed-From-To: analyzed->closed
State-Changed-By: cae
State-Changed-When: Mon May  5 14:43:39 2003
State-Changed-Why:
    This is not a bug. According to the standard, the behaviour is
    undefined, if one tries to instantiate an STL-template with an
    incomplete type. gcc accepts this code and does the right thing,
    if concepts checks are disabled at compile time. If concepts checks
    are enabled, there is additional code that checks that STL template
    parameters meet the requirements of the standard. As an incomplete
    type doesn't meet these requirements, the code is rightfully rejected.
    
    See the diskussion following http://gcc.gnu.org/ml/gcc/2003-04/msg01516.html
    on the gcc-Mailinglist for more details.
