[Bug c/13382] New: Type information for const pointer disappears during optimisation.

["richard dot hutchinson at asa dot co dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling the source code

static const struct
{
  int aMember;
} *const aPointer = 0;

int main()
{
  int anInt = (aPointer == 0) ? 0 : aPointer->aMember;
  return 0;
}

with the command line

gcc -o prog -O prog.c

generates the following error output:

testgcc.c: In function `main':
testgcc.c:15: error: request for member `aMember' in something not a structure
or union

This does not happen if the -O switch is omitted.

This behaviour does not occur with gcc 2.95.3 (the only other Solaris version I
have to hand).
