            Bug ID: 57915
           Summary: ICE in set_address_disp, at rtlanal.c:5537
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: etienne_lorrain at yahoo dot fr

On latest Fedora, with: gcc version 4.8.1 20130603 (Red Hat 4.8.1-1) (GCC)
I get:
  $ /usr/bin/gcc -m32 -Os bug.c
  bug.c: In function ‘menu’:
  bug.c:59:1: internal compiler error: in set_address_disp, at rtlanal.c:5537
   }
   ^
  Please submit a full bug report,

possibly related to  asm(... "X" (*str)) , I use "X" mostly because I had
problems using "m" when the pointer points to local variable on the stack.
The problem do not exists with previous compiler versions, not a new code.

The simplified source code I finished to get after few hours is:

$ cat bug.c
extern inline const char *
_strnchr (const char *str, char c, unsigned size)
{
  asm ("cld ; repne scasb %%es:(%%edi),%%al"
    : "+c" (size), "+D" (str): "a" (c), "X" (*str):"cc");
  return str - 1;
}

extern inline unsigned
strlen (const char *str)
{
  return _strnchr (str, '\0', (~0)) - str;
}

extern inline void
_strncpy (char *dst, const char *src, unsigned nb)
{

  unsigned len = strlen (src);
  if (len > nb)
    len = nb;

  __builtin_memcpy (dst, src, len);
  dst[len] = '\0';

}

extern inline char *
strcpy (char *dst, const char *src)
{
  _strncpy (dst, src, (~0));
  return dst;
}

typedef struct
{
  char go_msg[8];
  char scanpath[16];
} gujin_param_t;

extern gujin_param_t copy_gujin_param;
enum { kernel_bottom_menu, setup_bottom_menu } type;

unsigned short getkey(void);
unsigned timeout;
unsigned menu (void)
{
    char local_scanpath[sizeof (copy_gujin_param.scanpath)];
    strcpy (local_scanpath, copy_gujin_param.scanpath);

    for (;;)
      {
    unsigned short key = getkey();
    if ((type == kernel_bottom_menu) ? (key == (0x1312)) : key == (0x3900 | '
'))
      {
        strcpy (local_scanpath, copy_gujin_param.scanpath);
      }
      }
}
