Hi, I would like to use placement to instantiate a C++ object into a shared memory segment and access that object from a second process. When I test with an integer, the integer is accessible from the second process. But when I instantiate a C++ class object, it seems a memory pointer, which is local within the first process, is placed in memory. The place object is fully accessible and usable in the first process. I am guessing that the pointer points to the class definition within a table local to that first process. Unfortunately, that table, which does not seem to exist at the same address in the second process, causes the second process to Seg fault when it attempts to access the object instantiated in shared memory. What is the current correct approach to instantiating objects in shared memory so that multiple processes can access the C++ objects? Thank you. gcc --version gcc (GCC) 3.4.3 Copyright (C) 2004 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
