Hi,
Ok solved it myself - segfaulting on line 147 of umount.c
path = xmalloc_realpath(zapit);
Looking back through the changes, this commit is breaking it, (reversing
it fixes)
-#if defined(__GLIBC__) && !defined(__UCLIBC__)
+#if defined(__GLIBC__) || \
+ (defined(__UCLIBC__) && UCLIBC_VERSION >= KERNEL_VERSION(0, 9, 31))
I am using uClibc 0.9.29 , which seems to make the logic the same, as
both eval false (I changed 0, 9, 31 to lower but no different)?
Cheers
Rich

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
