[boost] [ineterprocess] managed mapped file - recovery from process failure

Hi, I have noticed that if a process is killed while it's allocating memory from a managed file, later loading of the managed file may segfault (even in read-only mode). A. What is the expected behaviour in this case? B. Should such a segfault be considered as a bug or is it the case that the user is not supposed to use the managed file after process failure? C. If unsupported, any pointers on efforts to improve this? Thx, Assaf
