#include <chrono>
int main()
{
(void) std::chrono::locate_zone("Asia/Chungking");
}
```
With the latest tzdata (version 2024a-2) on Debian Sid this fails:
terminate called after throwing an instance of 'std::runtime_error'
what(): tzdb: cannot locate zone: Asia/Chungking
Aborted (core dumped)
The problem is a Debian patch that enables link chaining, so that one link can have another link as its target:
https://sources.debian.org/patches/tzdata/2024a-2/ziguard.awk-Move-link-to-link-feature-from-vanguard-to-ma.patch/
This feature was added to tzdata in 2022, but isn't compatible with the expectations of the C++20 standard. When chrono::locate_zone finds a link, it expects its target to be a zone, not another link. |

[ Test Plan ]
1. Create `testcase.cpp`:
```
#include <chrono>
int main()
{
(void) std::chrono::locate_zone("Asia/Chungking");
}
```
2. Compile: `g++ -std=c++20 -o testcase testcase.cpp`
3. Run: `./testcase`
The test case should not crash. |
