7235,mapped_region not accepting size = 0,matthieu.dorier@…,Ion Gaztañaga,"Since Linux 2.6.12, and on other platforms, mmap is supposed to fail if the specified ""size"" parameter is 0. This causes some problems in all the Boost.Interprocess library since pretty much all the high-level structures (managed_shared_memory, for instance) use mapped_region (thus mmap) with size = 0, usually when the object is created with the ""open_only"" flag.

I have observed this bug on BlueGene/P's CNK environment, with gcc 4.1.2. It seems logical to me that, when opening an existing shared structure, the size doesn't have to be known. I don't have any solution yet...",Bugs,new,To Be Determined,interprocess,Boost 1.50.0,Problem,,mmap,
