Memory leak in SIL.DictionaryServices.Lift.LiftWriter #880

Open johnthagen opened 3 years ago

johnthagen commented 3 years ago

Our usage of <PackageReference Include="SIL.DictionaryServices" Version="7.0.0-alpha0822"> SIL.DictionaryServices.Lift.LiftWriter leaks memory each time a project is exported (~2-10MB?). This seems to leak logarithmically, as in, if you export the same project over and over it leaks less memory each time. It's unclear what can be done. It may require upstream fixes.

Related to #811, follow on to #688
