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.
Program terminated with signal 11, Segmentation fault.

4097 unlink(av, nextchunk, bck, fwd);
(gdb) bt
