From: jkanze@caicheuvreuse.com To: gcc-gnats@gcc.gnu.org Subject: libstdc++/10082: Wrong semantics in uninitialized_fill_n Date: Fri, 14 Mar 2003 14:56:00 -0000 [thread overview] Message-ID: <20030314145035.25908.qmail@sources.redhat.com> (raw) >Number: 10082 >Category: libstdc++ >Synopsis: Wrong semantics in uninitialized_fill_n >Confidential: no >Severity: serious >Priority: medium >Responsible: unassigned >State: open >Class: rejects-legal >Submitter-Id: net >Arrival-Date: Fri Mar 14 14:56:01 UTC 2003 >Closed-Date: >Last-Modified: >Originator: James Kanze >Release: g++3 (GCC) 3.2.2 >Organization: >Environment: 054@~/tmp/news (98): uname -a SunOS padev054 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-5_10 >Description: The compiler fails to compile the attached legal code. The reason for this is that the library has not implemented uninitialized_fill_n (and presumably uninitialized_fill) in a conforming manner.
