Jere,

The problem is that PROJ is compiled with the default C library (LIBC) and
your application is presumably built with the debug C runtime DLL (MSVCRTD).
I would suggesting linking against the PROJ stub library (for the DLL)
instead of the static library.  The stub library should be proj_i.lib.

Alternatively you can rebuild PROJ with the same C library options as your
main project.  I think you would want to add /MDd to the CFLAGS definition
in makefile.vc.

Best regards,
