Valgrind can't *quite* handle Adobe InDesign yet

[Dan Kegel]

http://bugs.kde.org/show_bug.cgi?id=126389
means that valgrind can't yet handle apps that
throw exceptions during regular operation.
Like, say, Adobe InDesign's installer.
I would like to valgrind that to track down
http://bugs.winehq.org/show_bug.cgi?id=11757
but I can't because valgrind doesn't handle fxrestor.
I think, anyway...

For debugging you can disable use of fxrstor with this:

diff --git a/dlls/ntdll/signal_i386.c b/dlls/ntdll/signal_i386.c

Thanks.  What's the downside?   I imagine apps that use floating
point inside exception handlers will break?

Floating point will still work, but apps using the MMX/SSE registers will
break.
