In commit 71b9a45330fe220d1 we changed the condition we use to determine whether we need to refill the TLB in get_page_addr_code() to if (unlikely(env->tlb_table[mmu_idx][index].addr_code != (addr & (TARGET_PAGE_MASK | TLB_INVALID_MASK)))) { This isn't the right check (it will falsely fail if the input addr happens to have the low bit corresponding to TLB_INVALID_MASK set, for instance). Replace it with a use of the new tlb_hit() function, which is the correct test.
