--- Comment #7 from Esme Povirk <madewokherd at gmail.com> ---
After that, the winforms code tries to call a COM method with an object[]
parameter:

Method (wrapper managed-to-native) int
System.Windows.Forms.UnsafeNativeMethods/IHTMLDocument2:Write
(intptr,object[],int&) emitted at 24eeef08 to 24eeefe0 (code length 216)
[Windows-ISO-Downloader.exe]
type 0x1c not handled
* Assertion: should not be reached at
/home/wine/wine-mono/mono/mono/metadata/marshal.c:668

The assert is in mono_array_to_lparray_impl.

Method definition:

int Write([In, MarshalAs(UnmanagedType.SafeArray)] object[] psarray);

In theory, this should be marshaled as a safearray of string, not object. I'm
also not sure why mono_array_to_lparray_impl is being called when this method
expects a safearray.
