I have pushed commit that (hopefully) explains the situation.
We have to be more careful when LLDB is running on big-endian machine. Below we
call `llvm::LoadIntFromMemory` function. On big-endian machine that function
reads from the provided region of memory in 64-bit (i.e. 8 byte) chunks. We
must ensure that the whole value is stored in a memory region whose size a
(smallest) multiple of 64-bit (i.e. 8 bytes).
