           Summary: new T({""}) crashes G++ when struct T { std::string
                    foobar };
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: peter.schmidt-nielsen@cba.mit.edu


Created attachment 24482
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24482
Minimal test case producing the (un)desired behavior, and temporary files.

The following code:

#include <string>

struct T {
    std::string foobar;
};

T* x = new T({""});

Produces the following behavior:

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions.

I listed the affected version as 4.7.0 because when I went on IRC, I was
informed by a user there that 4.7.0 20110524 (experimental) [trunk revision
174141] is still affected.

System information:

peter@magma:~$ uname -a
Linux magma 2.6.31-23-generic #75-Ubuntu SMP Fri Mar 18 18:16:06 UTC 2011
x86_64 GNU/Linux
peter@magma:~$ cat /etc/issue
Ubuntu 9.10 \n \l

Attached is the code and the temps.

Confirmed.  4.3 rejected the code, so does the EDG frontend of ICC 12.0:

t.C(7): error: expected an expression
  T* x = new T({""});

so not sure if it is valid code or not.

it's only valid in C++0x
