[I] [C++] arrow::compute::Function::default_options() returns nullptr for "rank" on Ubuntu [arrow]
tikkss opened a new issue, #46299:
URL: https://github.com/apache/arrow/issues/46299
### Describe the bug, including details regarding any error messages, version, and platform.
Steps to reproduce:
Run the following program on Ubuntu (reproduced on Ubuntu 24.04 using the official packages):
```c++
// g++ -g3 -O0 a.cc $(pkgconf --cflags --libs arrow) && ./a.out
#include <stdio.h>
#include <arrow/compute/api.h>
int
main(void)
{
auto func = *(arrow::compute::GetFunctionRegistry()->GetFunction("rank"));
printf("%p\n", func->default_options()->options_type());
return 0;
}
```
Expected result:
A valid pointer to a FunctionOptions object, specifically arrow::compute::RankOptions.
Actual result:
Returns `nullptr`.
Environments:
* Arrow version: 20.0.0
* OS: Ubuntu 24.04 (Debian noble)
* This does not reproduce on other platforms.

It seems that `arrow::compute::RankOptions::Defaults()` may be called https://github.com/apache/arrow/blob/81bb98853c5c84132dc1ae9cd1be8507bdd0800a/cpp/src/arrow/compute/kernels/vector_rank.cc#L386
before `arrow::compute::internal::kRankOptionsType` is initialized https://github.com/apache/arrow/blob/81bb98853c5c84132dc1ae9cd1be8507bdd0800a/cpp/src/arrow/compute/api_vector.cc#L154-L157 .
`arrow::compute::internal::kRankOptionsType` is used in `arrow::compute::RankOptions::RankOptions()` that is used by `RankOptions::Defaults()`:

@pitrou @bkietz Do you know whether there is the static variable initialization order specification for C++ or not?
