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:

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.

Attached is the code and the temps.
