[Bug c++/36794] New: Internal compiler error: Segmentation fault, when incorrectly using __attribute__ ((packed))

["vanco dot gccbugzilla at vancomaja dot com" <gcc-bugzilla at gcc dot gnu dot org>]

A funny use of __attribute__ ((packed)) caused a seg fault. 
Code: 
====== (see attachment for full preprocessed file)
struct wrap_a {int a;};
struct wrap_b {long b;}; // note: 64bit machine
typedef std::pair<wrap_a __attribute__ ((packed)), wrap_b> my_pair; // crash!
======
Command line: 
g++ /tmp/g++bug.cc
======
Output: 
/tmp/g++bug.cc: In function ?int main()?:
/tmp/g++bug.cc:11: internal compiler error: Segmentation fault
