Bug #: 51004
Summary: ICE in lower_stmt at gimple-low.c:428
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: kennytm@gmail.com
Test case:
===========================================
#include <boost/python/object_core.hpp>
struct CCC
{
int x;
};
typedef boost::python::object S;
int extract(S obj)
{
return 0;
}
void init_from_tuples_impl(S tpl)
{
new CCC{extract(tpl)};
}
void tuples()
{
&init_from_tuples_impl;
}
===========================================
It should compile with no error. Instead, the compiler fails with error
message:
$ g++ -std=c++0x -c 2.cpp `pkg-config --cflags python3`
2.cpp: In function ‘void init_from_tuples_impl(S)’:
2.cpp:23:1: internal compiler error: in lower_stmt, at gimple-low.c:428
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.archlinux.org/> for instructions.
(It should be possible to remove the dependency on Boost.Python, but I haven't
have time to do so yet).
gcc config:
$ g++ -v
Using built-in specs.

Even if you can't reduce the testcase (maybe via 'delta'? See:
http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction) please attach anyway the
preprocessed *.ii, per http://gcc.gnu.org/bugs/

Created attachment 25741
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25741
The processed file that triggers the bug.
Reduced test case:
=====================================
struct CCC
{
int x;
};
struct S
{
~S() {}
};
void init_from_tuples_impl(S* tpl)
{
new CCC{ (S(*tpl), 0) };
}
=====================================
$ g++ -c 2.cpp
2.cpp: In function ‘void init_from_tuples_impl(S*)’:
2.cpp:13:9: warning: extended initializer lists only available with -std=c++0x
or -std=gnu++0x [enabled by default]
2.cpp:14:1: internal compiler error: in lower_stmt, at gimple-low.c:428
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.archlinux.org/> for instructions.
=====================================
The .ii file is the same, attached for completeness.

Thanks. Mainline works fine and doesn't look like a regression.
