This also breaks lto-bootstrap on i686-pc-cygwin:

/gnu/gcc/gcc/libcpp/lex.c: In function ‘search_line_sse2’:
/gnu/gcc/gcc/libcpp/lex.c:370:15: internal compiler error: in convert_move, at
expr.c:326

In the call to convert_move, we have:

to = (reg/v:V16QI 62 [ repl_nl ])
from = (mem/u/c:BLK (reg/f:SI 97) [0 MEM[(const v16qi *)&repl_chars]+0 S16
A128])
