[Bug c++/30637] The options -fno-unit-at-a-time and -finline-functions generates erroneous code

[reichelt at gcc dot gnu dot org]

------- Comment #6 from reichelt at gcc dot gnu dot org  2007-02-09 01:16 -------
The bug has nothing to do with -fno-unit-at-a-time.
(It is ignored for C++ anyways.)

The bug is fixed since GCC 4.0.0.

Btw, here's a shorter self-contained program that hangs when compiled with
"g++ -O -finline-functions" by GCC 3.4.x:

====================================
struct A
{
   virtual void FOO() {}
};

struct B
{
  A* p;

  B() : p(new A) {}

  A* foo();
  void bar();
};

A* B::foo()
{
  return p;
}

void B::bar()
{
  foo()->FOO();
}

int main()
{
  B().bar();
  return 0;
}
====================================
