[Bug c++/27648] New: ICE on alias attribute casting

[thor at math dot tu-berlin dot de]

Enter the following program:

int main(int argc,char **argv)
{
  float x = 0.9;
  long y  = reinterpret_cast<long &>(static_cast<float
&__attribute((may_alias))> x);

  return y;
}

and compile with 

$ g++-4.0 -O3 -Wall aliastest.cpp

Result is:

aliastest.cpp: In function 'int main(int, char**)':
aliastest.cpp:4: internal compiler error: Segmentation fault
