Description

OS: RHEL4, gcc 3.4.3

A process creates a named shm segment by instantiating class managed_shared_memory with create_only mode set and unrestricted permissions (-rw-rw-rw-) Another process launched by the same user attaches the shm using open_only mode. Permissions of the shm segment get changed (-rw-r--r--)
