When writing modules made up of multiple cmod files, the top level module class has to have CVARs before PIKEVARS, otherwise the module will cause a segfault when loading. The following module dumps core (condensed to one file for clarity), but if the CVAR and PIKEVAR are swapped, loads properly.

module.cmod:

typedef struct
{
    int t;
} OBJECT_DATA;

CVAR OBJECT_DATA   *object_data;
PIKEVAR int i;

pike_init_pam_main()
{
    OBJECT_DATA * dta;

    dta =
        (OBJECT_DATA*)malloc(sizeof(OBJECT_DATA));
    if (!dta)
        Pike_error("init_test: Out of memory!\n");

    THIS->object_data = dta;
}

pike_exit_pam_main()
{
  if(THIS->object_data)
  {
    free(THIS->object_data);
  }
}


void pike_module_init()
{
  INIT
  pike_init_pam_main();
}

void pike_module_exit()
{
  EXIT
  pike_exit_pam_main();
}
