[Bug c++/41619] [4.4/4.5 regression] ICE in insert_save (caller-save.c) for SPEC CPU2000's 252.eon

[reichelt at gcc dot gnu dot org]

------- Comment #3 from reichelt at gcc dot gnu dot org  2009-10-30 15:52 -------
Confirmed. Even shorter testcase (crashes with "-O2
-fno-ira-share-save-slots"):

==========================
struct A
{
  A(double);
};

int foo();

A bar(double x)
{
  double y;
  if (foo())
    y = 1 / x;
  return y;
}
==========================

bug.cc: In function 'bar(double)':
bug.cc:14:1: internal compiler error: in insert_save, at caller-save.c:1223
Please submit a full bug report, [etc.]

The code compiles with GCC 4.4.0, but crashes since GCC 4.4.1.
