--- Comment #1 from Michael Meissner <meissner at gcc dot gnu.org> ---
The example only shows the bug with big endian, 32-bit without optimization=
.=20
If you optimize the code, the array assignment goes away.  Here is a better
example that can be optimized:

extern void foo (char *);

void
g4 (void)
{
  char zj[] =3D "XXXXXXXXXXXXXXXX";
  foo (zj);
}

With the current trunk (as of May 27th) the new example fails at no
optimization, -O1, and -O2.=
