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.
