Package: g++-4.7 Version: 4.7.1-2 Severity: important g++ ends with ICE on following test code:
===start=== #include <functional> struct User { void run(void *) {} }; int main() { User u; std::function<void()> p = std::bind(&User::run, &u, nullptr); } ===end=== $ g++ -std=c++11 -c -O test.cpp test.cpp: In constructor ‘std::function<_Res(_ArgTypes ....)>::function(_Functor, typename std::enable_if<(! std::is_integral<_Functor>::value), std::function<_Res(_ArgTypes ....)>::_Useless>::type) [with _Functor = std::_Bind<std::_Mem_fn<void (User::*)(void*)>(User*, std::nullptr_t)>; _Res = void; _ArgTypes = {}; typename std::enable_if<(! std::is_integral<_Functor>::value), std::function<_Res(_ArgTypes ...)>::_Useless>::type = std::function<void()>::_Useless]’: test.cpp:12:1: internal compiler error: in type_contains_placeholder_1, at tree.c:2957 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions. Preprocessed source stored into /tmp/ccTlnebC.out file, please attach this to your bugreport. Seems related to optimization and nullptr in args. When nullptr is replaced with (void *)0, gcc compiles the code successfully. -- System Information: Debian Release: wheezy/sid APT prefers testing-proposed-updates APT policy: (500, 'testing-proposed-updates'), (500, 'testing'), (400, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.3.6+ (SMP w/4 CPU cores; PREEMPT) Locale: LANG=pl_PL.UTF-8, LC_CTYPE=pl_PL.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages g++-4.7 depends on: ii gcc-4.7 4.7.1-2 ii gcc-4.7-base 4.7.1-2 ii libc6 2.13-33 ii libgmp10 2:5.0.5+dfsg-2 ii libmpc2 0.9-4 ii libmpfr4 3.1.0-5 ii libstdc++6-4.7-dev 4.7.1-2 ii zlib1g 1:1.2.7.dfsg-13 g++-4.7 recommends no packages.
