I've seen a lot of:
int fd = open(...);
size = lseek(fd, 0, SEEK_END);
lseek(fd, 0, SEEK_SET);
data = malloc(size);
read(fd, data, size);
close(fd);
Why not fstat? I don't know. Perhaps a case of cargo culting,
perhaps a case of "other unixes suck for portability"[1]. But it's
probably still there a lot in real code.
