 Martin Margo says:
 I learned std::string class is not binary compatible between my
 driver project (VC2008 IDE) and Xapian (built using nmake). I have in my
 compile option '_DEBUG'. Once I changed my configuration manager to
 'Release/Win32' and transferred proper header and include lib dirs, my
 program runs successfully.

 Olly comments:

 There are similar issues with GCC and _GLIBCXX_DEBUG which we handle by
 generating a check in "include/xapian/version.h" that the setting of
 _GLIBCXX_DEBUG is the same as it was when the library was built - e.g.if
 you build the library without _GLIBCXX_DEBUG, version.h contains:

 {{{
 #!cpp
 #ifdef _GLIBCXX_DEBUG
 #error You are compiling with _GLIBCXX_DEBUG defined, but the library
 #error was not compiled with this flag. The settings must match or your
 #error program will not work correctly.
 #endif
 }}}

 It would be nice to have a similar check for _DEBUG under MSVC.

Comment:

 No API or ABI issues (in fact this is catching an incompatible ABI issue)
 so suitable for 1.2.x.
