From: "sebor at roguewave dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/35711] New: bad text in -Wcast-qual warning (forgets volatile) Date: Wed, 26 Mar 2008 20:14:00 -0000 [thread overview] Message-ID: <bug-35711-1186@http.gcc.gnu.org/bugzilla/> (raw) [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #1: Type: text/plain, Size: 837 bytes --] The text of the warning below is incorrect and misleading -- the cast actually casts away the volatile qualifier, not constness. The warning is misleading when the type of the source is both const and volatile qualified. $ cat t.cpp && g++ -c -Wcast-qual t.cpp int* foo (volatile int *p) { return (int*)p; } t.cpp: In function int* foo(volatile int*): t.cpp:3: warning: cast from type volatile int* to type int* casts away constness -- Summary: bad text in -Wcast-qual warning (forgets volatile) Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: sebor at roguewave dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35711
