[smooth] Fix GCC LTO crashes on Windows. 

Fixes #1164 by using a volatile variable around `setjmp`.  It is hard to
say how this fixes crashes related to certain link-time optimizations.
This does not decrease the rendering performance.

* src/smooth/ftgrays.c (gray_convert_glyph_inner): Use volatile `error`.
