Descripción

### Describe the issue

gcc's STL implementation suffers the same problem, see [issue](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70298) for details.
I'm wondering if abseil team plans to resolve it.

### Steps to reproduce the problem

[This](https://gcc.gnu.org/bugzilla/attachment.cgi?id=38026) is the link to reproduce STL's issue, replacing with the abseil implementation could reproduce as well.
