[PATCH v2 0/1] MR9804: ntdll: Allow region allocation for some non growable heaps.
Thanks to Bernhard Übelacker for debugging this issue. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=55176 --- We could alternatively do this based on a Windows version check, but it doesn't seem very convenient and it's probably even harmless to allow allocations here, it's just not what any Windows version after Windows 95 does. -- v2: ntdll: Allow region allocation for some non growable heaps. https://gitlab.winehq.org/wine/wine/-/merge_requests/9804
