I couldn't figure out the best area label to add to this issue. Please help me learn by adding exactly one area label.

Crashing function is mono_free_bstr, though locally bstr looks like a sane value (0x7fc5b9d14168):

        g_free (((char *)bstr) - 4);

I guess this is an invalid address to free so malloc is throwing an ABRT?

The test is RunStringTests in CommonStringTests.cs, with the problematic function being this:

    [DllImport(NativeLibraryName)]
    public static extern void Reverse([MarshalAs(StringMarshalingType)] string original, [MarshalAs(StringMarshalingType)] out string reversed);

No idea why it fails.

@fanyang-mono - we want to validate in any recent main build and see the latest state of the test.
