Here is a small testcase:

[hjl@gnu-34 rrs]$ cat pr19427.c
void jumpfunc(int copy, void *p)
{
 void *l = &&jumplabel;
 if (copy)
  __builtin___memcpy_chk (p, l, 128, __builtin_object_size (p, 0));
jumplabel:
 return;
}
[hjl@gnu-34 rrs]$ /export/gnu/import/rrs/155319/usr/bin/gcc -S -O2 pr19427.c
pr19427.c: In function ‘jumpfunc’:
pr19427.c:5:26: internal compiler error: in emit_block_move_hints, at
expr.c:1197
