Confirmed, a little more reduced testcase:
typedef unsigned int uint32_t;
union double_union
{
double d;
uint32_t i[2];
};
int *_Jv_s2b (void);
int *_Jv_Balloc (int);
double _Jv_strtod_r (int *ptr, char *se, int e1, union double_union rv0, int
sign, long y)
{
union double_union rv;
int *bd = 0 , *bd0 = 0;
if (e1 > 308)
{
ovfl:
(rv.i[1]) = 0x7ff00000L;
(rv.i[0]) = 0;
if (bd0)
goto retfree;
goto ret;
}
if (!rv.d)
rv.d = 0.;
bd0 = _Jv_s2b ();
for (;;)
{
bd = _Jv_Balloc (*bd0);
if (!rv.d)
goto retfree;
if (y == ((uint32_t) 0x100000L) )
if (((rv.i[1]) & ((uint32_t) 0x7ff00000L))
>= ((uint32_t) 0x100000L) * (1994))
if ((rv0.i[1]) == (((uint32_t) 0xfffffL) | ((uint32_t)
0x100000L) * (2046))
&& (rv0.i[0]) == ((uint32_t) 0xffffffffL))
goto ovfl;
_Jv_Bfree1 ();
}
retfree:
_Jv_Bfree (ptr);
ret:
*se = 0;
return sign ? -rv.d : rv.d;
}
