[Lldb-commits] [PATCH] D93874: [process] fix exec support on Linux

[Jim Ingham via lldb-commits]

Thanks for looking into this further!  The thing to figure out is who still has a reference to either the Thread * or to the ThreadPlanStack over the destruction of the thread.  That shouldn't be allowed to happen.
