--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> 2012-09-05 18:25:56 UTC ---
It crashes at

(gdb) bt
#0  malloc_printerr (action=3, str=0x4a3079 "free(): invalid pointer", 
    ptr=0x6da000 <static_dtv>) at malloc.c:4950

(gdb) p dtv
$2 = (dtv_t *) 0x6da010 <static_dtv+16>
(gdb) 

Since dtv comes from,

static dtv_t static_dtv[2 + TLS_SLOTINFO_SURPLUS];

in csu/libc-tls.c,

  /* The array starts with dtv[-1].  */
#ifdef SHARED
  if (dtv != GL(dl_initial_dtv))
#endif
    free (dtv - 1); 

is incorrect.
