IM 6.5.2-9 Q16 Mac OSX Tiger.

Either of these worked fine in 6.5.2-8:
convert \( -size 200x200 xc:black \) \
\( -size 100x100 xc:white \) \
-gravity center -compose over -composite \
-alpha copy \
-background red -alpha background \
tmp_alpha2_red.png

or
convert \( -size 200x200 xc:black \) \
\( -size 100x100 xc:white \) \
-gravity center -compose over -composite \
+clone -compose copy_opacity -composite \
-background red -alpha background \
tmp_alpha2_red.png



but produces this in IM 6.5.2-9:

Anthony filed a bug report and we added a patch which we think addressed the issue. Find out if you and Anthony have different ideas about how -alpha background should work or if we applied the wrong patch.

OK. I have PMed Anthony about this to see what his viewpoint is. I liked having the transparent part go to background as before in IM 6.5.2-8. We will let you know once I hear back from him.

Go with what Anthony wants as there are other ways to get this functionality using -fill ... -opaque none

But see my new bug report at viewtopic.php?f=3&t=13854 which may be related
