Package: gcc-4.7 Version: 4.7.2-5 Severity: normal Dear Maintainer,
Compiling the following as C++ with -Wall: unsigned int n; union U { unsigned int x:8; } u = { n }; results in: $ gcc-4.7 -Wall -c test.cpp test.cpp:2:39: warning: narrowing conversion of 'n' from 'unsigned int' to 'unsigned char' inside { } is ill-formed in C++11 [-Wnarrowing] The type of the field U::x is not unsigned char: it is unsigned int. Since u.x and n have the same type, there is no narrowing conversion as defined in [dcl.init.list]. (See also <http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_closed.html#1461>) This bug seems to affect only unions, not ordinary structs. -- System Information: Debian Release: 7.0 APT prefers stable APT policy: (990, 'stable'), (500, 'oldstable-updates'), (500, 'stable'), (500, 'oldstable'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/12 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gcc-4.7 depends on: ii binutils 2.22-8 ii cpp-4.7 4.7.2-5 ii gcc-4.7-base 4.7.2-5 ii libc6 2.13-38 ii libgcc1 1:4.7.2-5 ii libgmp10 2:5.0.5+dfsg-2 ii libgomp1 4.7.2-5 ii libitm1 4.7.2-5 ii libmpc2 0.9-4 ii libmpfr4 3.1.0-5 ii libquadmath0 4.7.2-5 ii zlib1g 1:1.2.7.dfsg-13 Versions of packages gcc-4.7 recommends: ii libc6-dev 2.13-38 Versions of packages gcc-4.7 suggests: pn binutils-gold <none> ii gcc-4.7-doc 4.7.2-2 pn gcc-4.7-locales <none> ii gcc-4.7-multilib 4.7.2-5 ii libcloog-ppl0 0.15.11-4 pn libgcc1-dbg <none> pn libgomp1-dbg <none> pn libitm1-dbg <none> pn libmudflap0-4.7-dev <none> pn libmudflap0-dbg <none> pn libppl-c2 <none> pn libppl7 <none> pn libquadmath0-dbg <none> -- no debconf information -- To UNSUBSCRIBE, email to debian-gcc-requ...@lists.debian.org with a subject of "unsubscribe".
