[Bug]: UndefinedBehaviorSanitizer reports runtime error with recent Abseil versions

### Describe the issue

Starting with 91b7cd600a34cbd318c87196d7147c41197f8161 and at least up to 9bff2a9302a8dbf91712fc215eb2e2cf8ec234e7, when I run my project's tests with sanitizers enabled, an undefined behavior error is reported. Here's the report summary:

```

### Steps to reproduce the problem

With Docker installed:

```console
$ docker run -it envoyproxy/envoy-build-ubuntu:b0ff77ae3f25b0bf595f9b8bba46b489723ab446 bash
$ git clone https://github.com/abseil/abseil-cpp.git
$ git clone https://github.com/envoyproxy/envoy.git
$ export CC=/opt/llvm/bin/clang
$ export CXX=/opt/llvm/bin/clang++
$ cd envoy/mobile/
$ ./bazelw test --override_repository=com_google_absl=/abseil-cpp --test_output=all --test_env=ENVOY_IP_TEST_VERSIONS=v4only --config=asan //test/common/integration:client_integration_test
```

If you check out 90965f4c9662a73f2eb9c345b3a5431f40fd86d3 in `/abseil-cpp` and re-run the `./bazelw` command the tests pass with no UB reported. 91b7cd600a34cbd318c87196d7147c41197f8161 up to 9bff2a9302a8dbf91712fc215eb2e2cf8ec234e7 all report UB.

### What version of Abseil are you using?

* Last `master` commit without the undefined behavior: 90965f4c9662a73f2eb9c345b3a5431f40fd86d3
* First `master` commit with the undefined behavior: 91b7cd600a34cbd318c87196d7147c41197f8161
* Latest `master` commit verified to have the undefined behavior: 9bff2a9302a8dbf91712fc215eb2e2cf8ec234e7

### What operating system and version are you using?

* Operating System: Linux Ubuntu 20.04.5 LTS (Focal Fossa)
* Docker Image: `envoyproxy/envoy-build-ubuntu:b0ff77ae3f25b0bf595f9b8bba46b489723ab446`

### What compiler and version are you using?

```
clang version 14.0.0 (http://git.linaro.org/toolchain/jenkins-scripts.git 3157e5d15f6bcd69b98455f9a5bc31e34fdc6123)
