Conflict with the gtk4 gem


I get a segfault when running the following code:
```
#!/usr/bin/env ruby
require "gtk4"
require "trie"
t = Trie.new
```

If I remove "require "gtk4", then it works fine. Not sure if bug is in the gtk4 gem or the trie gem.

Requirements:
```
gem install fast_trie
gem install gtk4
```

Using ruby version ruby 3.1.4p223
