 Original ticket: https://github.com/GEOSwift/GEOSwift/issues/192

 Actual geos version is 3.7.1 but it's not one of the available options in
 Version field.

 Two threads invoke `GEOS_init_r()` which in turn invokes
 `geos::util::Interrupt::cancel()`. Both threads write to the requested
 variable, which is detected by the [Thread
 Sanitizer|https://developer.apple.com/documentation/code_diagnostics/thread_sanitizer]
 as a data race.
