Smaller testcase, without uninitialized variables too:
enum JSOp
{
JSOP_GETELEM = 5,
JSOP_LIMIT
};
extern void g ();
void
f (char *pc, char *endpc, int format, char ***fp, enum JSOp op)
{
while (pc <= endpc)
{
if ((fp && *fp && pc == **fp) || pc == endpc)
{
if (format == 1)
op = (JSOp) 256;
else if (format == 2)
op = (JSOp) 257;
else
op = JSOP_GETELEM;
}
if (op >= JSOP_LIMIT)
{
if (format)
g ();
}
}
}
