hi,
I have some code to deal with win32 dll under linux (also used in wine [1]). I
needs to emulate a few functions. There are some issues and I am running under
valgrind to see if it complains about something. And yes it does. I get this
warning for the code below. I have to admit that my asm knowledge is poor (and I
am aware that this is probably not the right place to ask). Still I try my luck
- does anyone see something wrong or can explain the warning?
Thanks
Stefan
