wine-1.3.16-74-g7ee63f0 and gcc -O0 console output

Slingplayer 2 crashes when clicking on "Log in" in the main window.  It
attempts to open a HTML page to log in to your account via the website.

=>0 0x7d52ce3f BindStatusCallback_create+0x2ba(This=0x74b3418, obj=0x32de18,
body=0x32ddf0) [/home/test/wine-git/dlls/msxml3/httprequest.c:503] in msxml3
(0x0032ddc8)

This only occurs when compiling Wine with gcc -O0.  It works fine with gcc -O1
and the precompiled .deb (which I believe to be -O2).

Workaround is to use native msxml3 OR compile with gcc -Ox where x>0.

Bug also does not exist with Wine-1.3.0 or Wine-1.2 with gcc -O3, but I cannot
recall this bug occurring before so could be a regression (perhaps even in
gcc).

Console output attached.
