[Bug middle-end/32950] [4.1/4.2 regression] ICE with __complex__ double

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #3 from reichelt at gcc dot gnu dot org  2007-12-27 20:06 -------
Confirmed. Reduced testcase that crashes on i686-pc-linux-gnu when compiled
with "-march=i386 -O" or "-march=i486 -O":

===========================================
struct A
{
  __complex__ double c;
};

struct B
{
  A a;
  B(A x) : a(x) {}
  void foo();
};

void bar()
{
  B b = A();
  B(b).foo();
}
===========================================

The bug is present since GCC 4.1.0, but seems to be fixed on mainline.
