bug report - umount segfault >= 1.22.0 MIPS/uClibc

[Richard Moore]

Hi,

umount has started segfaulting since >= 1.22.0 ,  (1.21.1 and earlier 
all ok).

Mount and everything else is fine. I am cross compiling with MIPS 
(uClibc) , this is the (not very helpful) strace.


open("/proc/mounts", O_RDONLY)          = 3
ioctl(3, TIOCNXCL, 0x7fd96b68)          = -1 ENOTTY (Inappropriate ioctl 
for device)
brk(0x4c9000)                           = 0x4c9000
read(3, "rootfs / rootfs rw 0 0\n/dev/root / squashfs ro 0 0\nproc /proc

read(3, "", 4096)                       = 0
close(3)                                = 0
readlink("/dev", 0x7fd94c18, 4095)      = -1 EINVAL (Invalid argument)
readlink("/dev/sda1", 0x7fd94c18, 4095) = -1 EINVAL (Invalid argument)
