`get_resident_set_size` computed RSS by multiplying the number of pages from `/proc/self/statm` with a hard-coded 4096-byte page size. This produces incorrect results on systems where the runtime page size is not 4 KiB. Use `sysconf(_SC_PAGESIZE)` to determine the actual page size at runtime so the RSS reported in `-Z time-passes` output is accurate across platforms.
