GCC 4.7.3 internal compiler error when using std::make_shared

[Thomas Voß]

GCC 4.7.3 crashes with an internal compiler error when trying to compile the following stripped-down test-case:

#include <memory>

namespace
{
struct Foo
{
    Foo(int) {}
};
}

int main(int, char**)
{
    auto foo = std::make_shared<Foo>();
    return 0;
}

Compiler command line is: g++ -std=c++11.

[Matthias Klose (doko)]

both 4.6 and 4.8 give correct error messages

[Doko-v (doko-v)]

works with 4.6 and 4.8, fails with the 4.7 branch

$ g++ -std=c++0x foo.cc

[Doko-v (doko-v)]

works with 4.7.2, fails with 4.7.3

[Sam Spilsbury (smspillaz)]

The error is actually more to do with trying to call a class constructor inside of make_shared that results in an error. For example, the following will also raise an internal compiler error:

#include <memory>

class Foo
{
    public:
        virtual ~Foo () = default;
        virtual void bar () = 0;
};

int main ()
{
    auto foo = std::make_shared <Foo> ();
    return 0;
}

[Rguenth (rguenth)]

works for me on the 4.7 branch (x86_64-linux) with preprocessed source from
using 4.7.2.

So it might be triggered by a libstdc++ change?

Can you attach preprocessed source?

[Doko-v (doko-v)]

Created attachment 29822
preprocessed source

[Rguenth (rguenth)]

Also fails with GCC 4.7.0 GCC 4.6 ICEs for me with

(confused by earlier errors)

4.5 seems to "work".

Factoring in libstdc++ changes the point of the regression.

[Jakub-gcc (jakub-gcc)]

GCC 4.6.4 has been released and the branch has been closed.

I also encountered similar situation where make_shared<> crashes but casting through new works.
Note that make_shared<> worked for object of another class. Attached file.

g++ (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3

Linux jeeves 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

g++ -c -I/usr/local/include -I ../include -std=c++11 EventWheel.cpp

[Jitendra Kulkarni (kulkarnij)]

I am on Ubunto 13.04.
The previous file (ccDenxuK.out) was with the statement:Event reset= *(Event::EventPointer(new Event()));
The current one is with the statement: Event reset= *(Event::EventPointer(make_shared<Event>()));

The following statement works:Event reset= *(Event::EventPointer(new Event()));

[Jitendra Kulkarni (kulkarnij)]

Correction: ccDenxuK.out was with: Event reset= *(make_shared<Event>();

[John-Paul Gignac (jp-gignac)]

This non-program causes the same internal error in gcc 4.7.3 (with -std=c++0x and -std=c++11). In general, it seems to happen any time I push_back an object with an inaccessible copy constructor.

#include <vector>

class A {
    A(const A&)=delete;
};

int main()
{
    std::vector<A>().push_back(*(A*)0);
    return 0;
}

Let's close this.
