I've been trying to get boost::bimap to work in a boost::interprocess::managed_mapped_file. I've attached two small programs. Both compile with g++ 4.7. One (multiindex.c++) puts a multi_index into the managed_mapped_file. On the first run, it creates the data structure puts some stuff in it, then reopens the data structure and outputs the stuff. On the second run, it does the same thing, but it uses the data stored in the mapped file. The other program (bimap.c++) does exactly the same thing, but when run the second time it crashes. My guess is because bimap isn't quite interprocess compatible---that is, it isn't using the provided allocator for EVERYTHING. Compiled with: g++ -o multiindex multiindex.c++ -lpthread and g++ -g -o bimap bimap.c++ -lpthread Any suggestions? Any chance of bimap being made interprocess compatible? Thanks! Joel
