Kernel 3.5.0 and user-space crash in closedir

Kernel 3.5.0 and user-space crash in closedir

[Ben Greear]

Hello!

I've a strange issue...on the 3.5 kernel (patched with my own hacks, including
some nfs stuff), I see user-space crashes in closedir().  Apparently due to
memory corruption in glibc.

I ran under valgrind and detect no errors.

I cannot reproduce the bug on 3.3.x kernels (with similar hacks applied).


I am curious if anyone has seen anything similar.
