It is back again! The following struct in my main module increases the  
executable size by 10MB with DMD 2.075:

struct Test {
	byte abcd[10 * 1024 * 1024];
}

It seems not to do so with *both* of these declarations, that create  
static arrays in the module:

byte abcd[10 * 1024 * 1024];
__gshared byte abcd[10 * 1024 * 1024];
