Subject: Kernel 3.5.0 and user-space crash in closedir
Date: Thu, 09 Aug 2012 09:18:00 -0700 [thread overview]
Message-ID: <5023E2B8.4060307@candelatech.com> (raw)
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.
