Likewise with
http://kegel.com/wine/valgrind/logs/2009-12-05-01.15/vg-d3dx9_36_core.txt
which shows the crash without a useful backtrace:

Invalid write of size 2
    at  ??? (in /dev/zero)
  Address 0x3f540000 is not stack'd, malloc'd or (recently) free'd
Unhandled exception: page fault on write access to 0x3f540000 in 32-bit code
(0x0d9289b1).
