Module: wine Branch: master Commit: 2fcb072f0376a24ca6d3faf0fc92bddf56c137ca URL: https://source.winehq.org/git/wine.git/?a=commit;h=2fcb072f0376a24ca6d3faf0f...

kernelbase: Use the same HLOCAL entry pointer alignment as native.
This changes the GlobalUnlock todo_wine as we previously considered the invalid mem handle as a valid pointer, and we now instead check handle validity.
Returning TRUE in for an invalid handle doesn't seem very important, and a corner case, and it breaks compatibility and imm32 tests.
