--- Comment #15 from ldk_linux deodato_art@yahoo.it 2008-09-09 09:53:27 --- Stefan (comment #5) pointed out that he bug came up after the following patch:
ntdll: Remove assumptions that the subheap is at the beginning of the memory block.
The change was made from Alexandre Julliard in wine 0.9.47, so maybe he would be able to explain this strange behavior when enlarging the size of SUBHEAP.
