A hex value of 0xDEADBEEF is a popular value for initializing areas of
memory when they are first allocated.  It's an easily-recognizable
pattern, which does not (in most systems) correspond to an actual,
valid user virtual or physical memory address.

This crash strongly suggests that some code has been passed an
uninitialized pointer.

lstat() is a system call, used to enquire about the type and status of
a file or symbolic link.

If I had to guess, I'd guess that one of the WINE DLLs is not
completely initializing a WIN32 data structure in the same way that ME
does, and that this is a data structure whose internal format has
changed between 95/98 and ME.
