Thanks. I will fix it by memcpy instead of dereferencing int* casted from char*.

For reference, I've had similar problems in the past. Usually it happens because the header needs to be aligned on a uint64_t to be read. The ELF section has 8-byte alignment, but that can be incorrect when extracting from something like an archive. I just make a copy in that case https://github.com/llvm/llvm-project/blob/main/llvm/lib/Object/OffloadBinary.cpp#L156.
