FreeLing v4.2.1 doesn't seem to respect the --flush parameter

[MartinHammarstedt]

I encountered compilation issues when trying to build FreeLing v4.2 on Ubuntu 24.10. After upgrading to FreeLing v4.2.1, the installation was successful, but the --flush parameter no longer seems to work as expected. Newlines are no longer treated as sentence boundaries, and I must add a period or another punctuation mark to trigger a response from FreeLing.

I'm running FreeLing with the following command: /usr/local/bin/analyze --ner --nec --outlv tagged --output json --nortkcon --nortk --flush -f /path/to/eng.cfg.
