### Describe the bug, including details regarding any error messages,
version, and platform.
I've seen on several PRs the AMD64 Windows MinGW MINGW64 C++ segfault when
runnin the following test:
```
The following tests FAILED:
84 - arrow-json-test (SEGFAULT) arrow-tests
unittest
```
The error doesn't show much (obvious with a segfault):
```
Start 84: arrow-json-test
