The broke struct initializers.
They are emitted to object files with a symbol size of 1 byte regardless of
their actual size.
Also I wonder why the initializer are now common symbols ('V') while they
previously were normal uninitialized variables ('B').

Test case

cat > bug.d << CODE
struct Buffer { ubyte[64 * 1024] buffer; }
CODE

dmd2.063.2 -c bug
nm -S bug.o
0000000000000000 0000000000010000 B _D4bug26Buffer6__initZ

// 1-byte size and weak object
dmd2.064 -c bug
nm -S bug.o
0000000000000000 0000000000000001 V _D4bug26Buffer6__initZ
