galipremsagar opened a new pull request #10257:
URL: https://github.com/apache/arrow/pull/10257
With the nvcc 11.2 compiler we have a segfault when we have a copy and move
assignment operator :
```
using Impl::operator=;
```
before a move-assignment operator:
```
Variant& operator=(Variant&& other) noexcept {
this->destroy();
other.move_to(this);
return *this;
}
```
A minimal repro :
With a segfault : https://godbolt.org/z/h9eYv6zas
Without a segfault : https://godbolt.org/z/oWhK5qPd8
In this PR, as a workaround, we have essentially re-ordered the
move-assignment of `Variant` before `using Impl::operator=;`.
