Many thanks for the super fast response guys. I'm at a different PC now but
I'll apply that patch tomorrow.
I applied that patch this morning and sure enough, it does fix the
problem. Thanks to Andrea for noticing it.
BTW... while reading the patch I noticed that, quite by accident, the
source file 'pixman-mmx.c' had somehow gotten excluded from my MSVC
build project, so I took the opportunity to add it. Although the build
still succeeds, I see several warnings of this form while building
'pixman-mmx.c':-
pixman-mmx.c(586) : warning C4799: function 'whatever' has no
EMMS instruction
I don't know if that means anything bad but I thought it wouldn't do any
harm flag it up. Here's a list of the affected functions:-
function 'expand_4xpacked565' has no EMMS instruction
function 'is_opaque' has no EMMS instruction
function 'is_equal' has no EMMS instruction
function 'to_uint64' has no EMMS instruction
function 'expand_4x565' has no EMMS instruction
function 'is_zero' has no EMMS instruction
function 'store8888' has no EMMS instruction
function
'fast_composite_scaled_bilinear_mmx_8888_8_8888_none_OVER' has no EMMS
instruction
function
'fast_composite_scaled_bilinear_mmx_8888_8_8888_pad_OVER' has no EMMS
instruction
I've no idea what it means but I hope that's useful.
John
