Hello Ion,
Title says it all really: the attached mini-program gives me a segmentation fault on ubuntu linux 8.04 with gcc 4.2.3 when trying to read back the shared memory between process invocations (trying a similar program on XP also fails). If the comments on lines 33/34 and 66-67/68-69 are swapped it works as expected. I've also tried and failed to get it working with my own types as well as std::string.
I think you need to use the appropriate allocator with the STL types -- and I think if you need to use the appropriate shared memory allocators for the things you need to keep in the shared memory segment(s). I took a look at your code, and you may have to specialize the string's allocator to use the Interprocess allocator types. HTH. -- Dean Michael C. Berris Software Engineer, Friendster, Inc.
