            Bug ID: 55615
           Summary: kernel32:heap - The 32-bit test_child_heap() fails on
                    Windows with UTF-8 locales
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32

Pare down the test

kernel32:heap - The 32-bit test_child_heap() fails on Windows with UTF-8
locales:

heap.c:3498: testing global flags 0x20, heap flags 00000040
heap.c:3317: Test failed: HeapValidate failed
heap.c:3326: Test failed: HeapValidate failed

See https://test.winehq.org/data/patterns.html#kernel32:heap

The failure happens in the call below:
        test_debug_heap( argv[0], FLG_HEAP_ENABLE_FREE_CHECK );

This failure is 100% reproducible but does not happen in the 64-bit tests. Also
a comparison of the Hindi, Hindi+UTF-8 and English (Arab Emirates)+UTF-8
results confirms that this is specific to UTF-8 configurations. Finally, note
that until 2023-09-15 the nightly Wine tests only ran the 64-bit tests in UTF-8
locales.
