With a recent build (gcc version 4.6.0 20100819 (experimental) (GCC)),
I see no crash:

$ g++ -std=c++0x test.cpp
/tmp/ccSLxvPo.o: In function `void f<>()':
test.cpp:(.text._Z1fIIEEvDpRKT_[void f<>()]+0x31): undefined reference
to `my_vector<int>::my_vector(std::initializer_list<int>)'
collect2: ld returned 1 exit status

I suspect we don't want to put a lot of effort into fixing C++0x
experimental support in GCC 4.4.x.
