I'm not sure if this is a homebrew issue or a issue that needs to be addressed upstream. Compiling weechat with the --with-guile option causes a guile plugin to be loaded at when weechat starts. When you quit weechat, this plugin causes a crash when unloaded (I can be more specific about the exact nature of this crash if necessary). I have worked around the issue by disabling this plugin.
