Is it really EINVAL like the error message suggests? The best I can do (without understanding it) is (1) if I use dtruss (should be equivalent to strace) on a, I get [macbook] f90/bug% 25210/0x2baef9e: lseek(0x3, 0x0, 0x1) = -1 Err#29 25210/0x2baef9e: lseek(0x3, 0xFFFFFFFFFFFFFFF4, 0x1) = -1 Err#29 (2) if I use it on b, I get [macbook] f90/bug% 25218/0x2baf031: lseek(0x3, 0x0, 0x1) = -1 Err#29 25218/0x2baf031: lseek(0x3, 0x4, 0x1) = -1 Err#29
