yy_cp is NULL because of these lines in ifcico/flagexp.y:
| #ifdef FLEX_SCANNER /* flex requires reinitialization */
| yy_init=1;
| #endif
In the generated flaglex.c, setting yy_init to 1 inhibits
initialization:
| static int yy_init = 0; /* whether we need to initialize */
...
| if ( !(yy_init) )
| {
| (yy_init) = 1;
...
