Hi The problem is caused by the use of the Singleton class - which is marked as thread-unsafe in the header.
In MergeScorer, a local instance of BleuScorer is created and then destroyed. BleuScorer descends from Scorer, which has a handle to the thread-unsafe "singleton" Vocabulary. There's been a lot of code changes since I last looked at this, but I would question whether MergeScorer needs to create and destroy a BleuScorer every time it does the scoring. Can't it just re-use the same instance? I also wonder why code known to be thread-unsafe is in a multi-threaded application, cheers - Barry On Tuesday 26 June 2012 08:50:59 Marcin Junczys-Dowmunt wrote: > Hi Tom, > Yes, checked a few minutes ago with the latest changes.
