A different issue that worries me about PIE is the impact on the available address space in 32-bit builds. For instance, people routinely configure Postgres to allocate a shared-memory area of a couple GB, so if either the program text or the stack get moved too much, configurations that used to work will break for lack of enough contiguous free address space. I haven't been able to find anything definitive about the worst-case address space wastage due to ASLR in 32-bit builds; anyone here know? regards, tom lane -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
