Description Daniel Karlsson 2001-07-28 20:36:12 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.6 i686)

Description of problem:
The following program makes g++ segfault when using options -g and -O.
Workaround: name the union, don't use -g or -O


How reproducible:
Always

Steps to Reproduce:
1.Save source to bug.cc
2.g++ -g -O -c bug.cc

	

Actual Results:  g++ internal error: segfault in A &A::func2(double &)

Expected Results:  g++ not segfaulting ;)

Additional info:

struct A {
  int func1();
  A &func2(double &);
};
 
int
A::func1()
{
  return 0;
}
 
A &
A::func2(double &arg)
{
  union {
    double x;
    char y[8];
  };
  y[0] = func1();
  arg = x;
  return *this;
}

I've fixed this in http://gcc.gnu.org/ml/gcc-patches/2001-08/msg00154.html.
Will be fixed in gcc-2.96-96.
