From: "redi at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug web/61054] Clearly note effect of memcpy optimization improvements in 4.9 changes Date: Sun, 04 May 2014 15:54:00 -0000 [thread overview] Message-ID: <bug-61054-4-Vs7ZlzreHg@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-61054-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=61054 --- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- N.B. as well as custom allocators it affects the built-in delete[], which performs an implicit null check that can be optimized away in buggy code. We documented it on that page because of case where that happened.
