File triggering the crash

Compiling the attached (which is from Wine) with -O2, I get

  file.c: In function 'MSVCRT_vfprintf_s':
  file.c:4026:1: error: invalid argument to gimple call valist
  # .MEM_3 = VDEF <.MEM_9(D)>
  ret_8 = MSVCRT_vfprintf_s.part.7 (file_2(D), format_5(D), valist);
  file.c:4026:1: internal compiler error: verify_gimple failed

This must have happened about three days ago.
