[Bug c++/43392] New: g++ 4.4.1 [C++0X]: segmentation fault with empty initializer list

["jt at toerring dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When trying to compile this program

#include <vector>

class Baz {
  private:
    int foo, bar;
  public:
    Baz(int a = 0, int b = 0) : foo(a), bar(b) {}
};

int main()
{
    std::vector<Baz> a = {{}, {1, 2}};
}

with

g++ -std=c++0x -W -Wall -o t t.cpp

the compiler crashes with the errror message

t.cpp: In function â??int main()â??:
t.cpp:12: internal compiler error: Segmentation fault

The critical point seems to be the empty initializer list in the first position
- if moved to a later position the program gets compiled without problems.
Using different flags does not seem to have eny effect.

Here's the complete output of 'gcc -v':

                           Best Regards, Jens

PS: Sorry, I don't see how I could append the 't.ii' file created with the
'-save-temps' option, that seems to be a bit too long for putting it directly
into this form...
