Howto debug c++ (SWIG) extension under Windows

This is not true. You *can* set breakpoints in release mode, make sure to
add debug information to your release build so you'll be able to see the
sources.
There are several cases (such as inlined functions) that you *can't* set
breakpoint to.

Just copy it (and msvcp71d.dll) from your c:\windows\system32 (or wherever
your windows is installed) to the "Debug" library (or to the Python install
library).

Yes. See above.

Just as above again.

If you still can't stop try "forcing" breakpoints using
    __asm int 3
in your code. This way you can even run it out of MSDEV and you'll get a
message box when the "breakpoint" it hit. Just open the debugger on it.

HTH.
