Help create maxSize sketch

I have whipped up a quick sketch I'll let you play with,

at the moment, it creates a 30k progmem block.

#define nothing

template< uint64_t C, typename T >
  struct LargeStruct{
    T Data;
    LargeStruct< C - 1, T > Next;
};
template< typename T > struct LargeStruct< 0, T >{ };

typedef LargeStruct< 150, uint32_t > Container; //600 bytes

PROGMEM LargeStruct< 50, Container > l_Struct; //Fills to 30k bytes


void setup()
  {
    volatile int i = ( int ) &l_Struct;
  }

void loop()
  {
    
  }

Binary sketch size: 30,748 bytes (of a 258,048 byte maximum)
