regression testing indicating the first bad commit
Wine 1.1.38 and later cause VB6 applications to crash and behave unexpectedly
in various circumstances.
iiUsage (free download from http://martybugs.net/iiUsage/) works fine on Wine
1.1.36 and earlier, but crashes when attempting to display the main form on
Wine 1.1.38 and later.
Regression testing indicates the first bad commit is 
  oleaut32: Realize the font in getter functions.
  cf602ca4228f954d7de3b8100cea8fad680ed7f2
To reproduce:
  -follow steps on http://martybugs.net/iiUsage/wine.cgi to install iiUsage
  -when iiUsage is first run, it'll crash when it attempts to load the main
form
As another example, attempting to set the .TabVisible(n) = false for a tabbed
dialog control (tabctl32.ocx) in a VB6 application works fine in Wine 1.1.36
and earlier, but in Wine 1.1.38 and later, it results in the following runtime
error:
  [451] Property let procedure not defined and property get procedure did not
return an object
Similarly, attempting to set the column width of an msflxgrd.ocx column to 0
results in the same runtime error.
The workaround is to copy oleaut32.dll from a WinXP box into
.wine/drive_c/windows/system32/, register it, and then use winecfg to use the
native oleaut32 library instead of the built-in library.
