Procedure entry point error when calling Fortran library functions from C++

I have a Fortran library that is beibg called from a C++ main program. It generally works fine except that when certain subroutines are included in the Fortran library, the following error message shows up while executing the C++ program:

Test.exe - Entry Point Not Found

The procedure entry point for_realloc_lhs could not be located in the dynamic link library libifcoremdd.dll.

Note that the subroutine that was added to the Fortran library is not being called or referenced by the C++ program. The mere presence of that subroutine in the library causes the above error to occur.

Any help would be greatly appreciated.
