Date: Mon, 08 Aug 2011 20:12:00 -0000	[thread overview]
Message-ID: <bug-50024-4@http.gcc.gnu.org/bugzilla/> (raw)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50024

           Summary: gcc crashes when using braced initialization in member
                    function of template
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: stiffy2@gmx.de


When compiling the example code below, gcc version 4.7.0 20110725
(experimental) crashes, if the -std=c++0x flag is supplied.


Source:

template< class T >
struct Container
{
    Container(){
        int* ptr = new int{}; // crash ahead
    }
};

int main() {
    Container< int > c;
}


Call to gcc and error message:

g++ -std=c++0x    template_error.cpp   -o template_error
template_error.cpp: In member function `void Container<T>::foo()':
template_error.cpp:16:40: internal compiler error: in cxx_eval_bare_aggregate,
at cp/semantics.c:6601

gcc Version:

% LANG=C g++ -v
Using built-in specs.

COLLECT_LTO_WRAPPER=/home/evnu/libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ./configure --enable-plugin --enable-cloog-backend=isl
--with-ppl --enable-__cxa_atexit --with-system-zlib --enable-shared
--enable-threads=posix --enable-languages=c,c++ --disable-multilib

Thread model: posix
gcc version 4.7.0 20110725 (experimental) (GCC)


Note:
    The example compiles if Container is not a template class.
