Summary: ICE with lambda return type deduction and
braced-init-list
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal

int main() {
for ( auto && s : []()
{ return { std::string( "first" ), std::string( "second" ) }; }() )
std::cout << s << '\n';

ildtice.cpp:7:61: internal compiler error: in make_decl_rtl, at varasm.c:1136
{ return { std::string( "first" ), std::string( "second" ) }; }() )

ildtice.cpp:7:61: internal compiler error: Abort trap: 6
g++: internal compiler error: Abort trap: 6 (program cc1plus)
C++11 5.1.2/4:
…

{ attribute-specifier-seqopt return expression ; }
…
The return statement doesn't match the pattern because a braced-init-list is
not an expression. Should be a proper error.
