* freetype2/src/gxvalid/gxvmod.c (GXV_TABLE_DECL): Mark local
	variable `_sfnt' as volatile since it must keep its value across
	a call to ft_setjmp.
	(gxv_validate): Same for local variables `memory' and `valid'.
	(classic_kern_validate): Same for local variables `memory',
	`ckern', and `valid'.

	* freetype2/src/otvalid/otvmod.c (otv_validate): Same for function
	parameter `face' and local variables `base', `gdef', `gpos', `gsub',
	`jstf', and 'valid'.

	* freetype2/src/sfnt/ttcmap.c (tt_face_build_cmaps): Same for
	local variable `cmap'.
