Summary: try to clean up the type conversions and hope it passes on windows. one interesting thing I learned is that bitshift operations are special: in `x << y`, the result type depends only on the type of `x`, unlike most arithmetic operations where the result type depends on both operands' types.

Summary: As raised in facebook#2265, the arena allocator will return memory that is improperly aligned to store a `std::function` on macOS. Oddly, I'm unable to tickle this bug without adding a `std::function` field to `struct ReadOptions`—but my proposal in facebook#2265 does exactly that. In any case, here's a simple reproduction. Apply this bogus patch to get a `std::function` into `struct ReadOptions` ``` --- a/include/rocksdb/options.h +++ b/include/rocksdb/options.h @@ -1035,6 +1035,8 @@ struct ReadOptions { // Default: 0 uint64_t max_skippable_internal_keys; + std::function<void()> foo; + ReadOptions(); ReadOptions(bool cksum, bool cache); }; ``` then compile `db_properties_test` *with ubsan* and run `ReadLatencyHistogramByLevel`: ``` $ make COMPILE_WITH_UBSAN=1 db_properties_test $ ./db_properties_test --gtest_filter=DBPropertiesTest.ReadLatencyHistogramByLevel ``` ubsan will complain about several misaligned accesses: ``` Note: Google Test filter = DBPropertiesTest.ReadLatencyHistogramByLevel [==========] Running 1 test from 1 test case.

This patch solves the problem by adjusting the allocator to derive the necessary alignment from `alignof(std::max_align_t)`, which is properly 16 bytes on my machine. As I mentioned in facebook#2265, none of RocksDB's tests will cause this unaligned access to actually abort the process, but, on macOS, linking CockroachDB against a version of RocksDB with the above patch and letting it run for just a few seconds will cause a SIGABRT. ``` Process 19792 stopped * thread #2, stop reason = EXC_BAD_ACCESS (code=EXC_I386_GPFLT) frame #0: 0x0000000004f5e78f cockroach`DBNewIter + 95 cockroach`DBNewIter: -> 0x4f5e78f <+95>: callq *0x28(%rax) 0x4f5e792 <+98>: jmp 0x4f5e79e ; <+110> 0x4f5e794 <+100>: movq -0x50(%rbp), %rcx 0x4f5e798 <+104>: movq %rax, %rdi (lldb) bt * thread #2, stop reason = EXC_BAD_ACCESS (code=EXC_I386_GPFLT) * frame #0: 0x0000000004f5e78f cockroach`DBNewIter + 95 ``` I'd get you a backtrace, but [Go doesn't include cgo debug information on macOS](golang/go#6942). I've also tried building against libc++ on Linux, where debug information would be available, but I can't seem to trigger the bug there. In any case, this PR both fixes the segfault in CockroachDB and fixes the warnings reported by ubsan.

a4a4a2d changed the contract of `TableReader::NewIterator()` to require `ReadOptions` outlive the returned iterator. But I didn't notice that `SstFileReader` violates the new contract and needs to be adapted. The unit test provided here exposes the problem when run under ASAN. ``` $ ./sst_file_reader_test --gtest_filter=SstFileReaderTest.ReadOptionsOutOfScope Note: Google Test filter = SstFileReaderTest.ReadOptionsOutOfScope [==========] Running 1 test from 1 test case.

We ran into a flake I could not debug so instead added assertions in
case it happens again.
Command was:
```
TEST_TMPDIR=/dev/shm/rocksdb COMPILE_WITH_UBSAN=1 USE_CLANG=1 OPT=-g SKIP_FORMAT_BUCK_CHECKS=1 make J=80 -j80 ubsan_check
```
Failure output was:
```

`GetOptionsFromString()` is included in `set_options_one_in` because its current behavior actually involves invoking `PrepareOptions()` on existing shared option objects that may be in-use by a DB. While this has known problems like facebook#10374, it is actually used in production and users are finding these problems before us. To prevent accidental coasting we should turn on the feature in stress/crash test to ensure we discover these problems before our users do. Test Plan: - Build with TSAN: `$ COMPILE_WITH_TSAN=1 make -j24 db_stress` - Repro some `GenericRateLimiter` race conditions: ``` $ ./db_stress -rate_limiter_bytes_per_sec=1048576 --set_options_one_in=100 --max_key=1000000 ...

Summary: I must have chosen trimming before frame 8 based on assertion failures, but that trims too many frame for a general segfault. So this changes to start printing at frame 4, as in this example where I've seeded a null deref: ``` Received signal 11 (Segmentation fault) Invoking LLDB for stack trace...
