d851fce4cb
Summary: This patch fixes a bug where initialization code for .bss segments was emitted in the memory initialization function even though the .bss segments were discounted in the datacount section and omitted in the data section. This was producing invalid binaries due to out-of-bounds segment indices on the memory.init and data.drop instructions that were trying to operate on the nonexistent .bss segments.
