Package: g++-4.3 Version: 4.3.2-1 Severity: minor Put the following ridiculous code in a .cpp file: <text>
struct Base { virtual const int stupid() = 0; }; struct Derived : public Base { virtual int stupid() { return 1; } }; </text> and run the compiler on it, with warnings. I get: <quote> $ g++ -O2 -Wall -Wextra -o spurious.o -c spurious.cpp spurious.cpp:1: warning: type qualifiers ignored on function return type spurious.cpp:2: error: conflicting return type specified for 'virtual int Derived::stupid()' spurious.cpp:1: error: overriding 'virtual const int Base::stupid()' make: *** [spurious.o] Error 1 </quote> Observe that the warning claims to ignore the spurious const. However, the error reveals that it was not ignored. Had it been ignored, the over-ride's return would have matched. The warning should say warning: spurious type qualifiers on function return type or something similar: it should not claim to ignore the type qualifier. The obvious fix is, of course, to fix the base class: however, if that is in a library not under my control, this isn't a practical option when I come to sub-class it. I am consequently obliged to duplicate the spurious type qualifier and, hence, get even more warnings about it :-( Priority is negligible, of course. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.26-1-686 (SMP w/2 CPU cores) Locale: LANG=en_GB.ISO-8859-15, LC_CTYPE=en_GB.ISO-8859-15 (charmap=ISO-8859-15) Shell: /bin/sh linked to /bin/bash Versions of packages g++-4.3 depends on: ii gcc-4.3 4.3.2-1 The GNU C compiler ii gcc-4.3-base 4.3.2-1 The GNU Compiler Collection (base ii libc6 2.7-16 GNU C Library: Shared libraries ii libgmp3c2 2:4.2.2+dfsg-3 Multiprecision arithmetic library ii libmpfr1ldbl 2.3.1.dfsg.1-2 multiple precision floating-point ii libstdc++6-4.3-dev 4.3.2-1 The GNU Standard C++ Library v3 (d g++-4.3 recommends no packages.
