Yes, it seems that your library->num_modules is 0. This variable is
updated each time a new module is added to the library. This usually
happens when calling:

  - FT_Add_Module, which is rarely called by applications

  - FT_Init_FreeType, which calls FT_Add_Default_Modules which
    calls FT_Add_Module for each one of the modules listed in
    FT_CONFIG_MODULES_H (a.k.a. <freetype/config/ftmodule.h> in
    most builds of the library)

    for more details, see src/base/ftinit.c

what is the content of your ftmodule.h file ??
