There is no such line in the latest version. You definately should be
running from the CVS version of the sources - that looks fairly old
(well, pre changes for 1.6 and later anyway)
Also, it appears you can not bee "below" the pfnInit call - ie, there
is no source available. This implies a debug/release mismatch - eg,
that you have a debug application, but a release win32ui, for example.
Although win32uiHostGlue.h is supposed to catch that, it may not.
All the pfn's used in this module are entry points into either
pythonxx(_d).dll or win32ui(_d).pyd - so you should be able to step
into each of them. In this case, the error will come from either
pythonxx_d.dll or pywintypesxx_d.dll - if you are seeing non _d
versions, fix that first!
Finally, pythonwin.cpp is a very small program, and uses this exact
same technique to boot Pythonwin. Thus, it is good sample code for
this purpose - what is different between your app and Pythonwin.cpp?
Does your built pythonwin.exe work?
