# Compiler Versions
GHC 8.8.x seems to have a GC issue which causes space leak in concurrent
streams especially when used with `-N` RTS option. The root cause of
this has not yet been established. The leak is not seen with earlier
versions of GHC.
GHC 8.2.2 may hog memory and hang when building certain application using
streamly (particularly the benchmark programs in the streamly package).
Therefore we recommend avoiding using the GHC version 8.2.x.
