Huh, that should read data+bss for usual elf binaries which share the two in one segment (and there seems to be some code around in other places that expect binaries formed with only two PT_LOAD segments). Assuming that, setting data_addr conditionally or unconditionally should not make any difference, it will always be set for the first data PT_LOAD segment and there will be only one (the other one will be text).
