Bug #: 50478
Summary: Internal compiler error when using initializer lists
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: bitti@iki.fi
The following short program shows the problem:
#include <set>
#include <string>
int main() {
std::set<std::string> s;
s.insert( {"abc", "def", "hij"} ); // This line is the problem
}
> g++ -std=c++0x test.cc
test.cc: In function ‘int main()’:
test.cc:6:37: internal compiler error: in joust, at cp/call.c:7646
If I compile with -pedantic, the program compiles fine.

The problem seem to exist in 4.7.0 20110917 (experimental) as well, pointing to
joust, at cp/call.c:7960.

Insane, this doesn't happen for an initializer list of 1, 2, 4, or 5 elements.
Happens with std::vector too, however. Should be rather easy to construct a
reduced testcase including only <string>.

This is enough:
namespace std
{
template<class _E>
class initializer_list;
template<typename _Key>
struct set
{
void insert(const _Key&);
};
struct string
{
string(const string&, __SIZE_TYPE__, __SIZE_TYPE__ = -1);
string(const char*);
string(initializer_list<char>);
};
}
int main()
{
std::set<std::string> s;
s.insert( { "abc", "def", "hij"} );
}

--- Comment #4 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-12-21 12:43:38 UTC ---
This is a more correct testcase, which also preserves the property of OT that
-pedantic works around the issue. Note: removing the string constructor taking
an initializer_list also works around the problem:
///////////////////
#include <initializer_list>
namespace std
{
template<typename _Key>
struct set
{
void insert(const _Key&);
void insert(initializer_list<_Key>);
};
struct string
{
string(const string&, __SIZE_TYPE__, __SIZE_TYPE__ = -1);
string(const char*);
string(initializer_list<char>);
};
}
int main()
{
std::set<std::string> s;
s.insert( { "abc", "def", "hij"} );
}

Fixed in 4.7.1 and mainline. Let's add the testcase and close the PR.
