The problem is caused by the application bug. It does:

str1 = SysAllocStringLen("Reply", 5);
SysFreeString(str1);
str2 = SysAllocStringLen(str1, 5);

i.e. it passes a just freed memory block as a string pointer to copy data
from. Wine allocates new memory block in the place of just freed one, and
simultaneously changes some internal data structures which happen to be
inside of a previously freed memory block, and that corrupts the passed in
data.

According to a snoop trace native oleaut32 doesn't do memory allocations
on each SysAllocStringLen call, and probably uses some internal cache.

I'd say this bug is a WONTFIX, please report the problem to the application
developers.
