For this "The binary being executed by the process does not have read permission enabled." -- is this when the binary permissions are changed after it starts running? I thought a core file was just a dump from RAM, does it really even need to open the ELF file again? 4) I noticed %P always gave me P1200 even after a reboot I recall, I had expected it be '1', do you see similar?
