Title:
crash during thread exit when using thread local storage
Status in eglibc package in Ubuntu:
New
Bug description:
An application we develop crashes on exit with:
*** Error in `foo': free(): invalid pointer: 0x09309bc0 ***
This issue occurs when there are a large number of threads running
which use thread local storage. We have identified the issue as an
existing upstream glibc bug, #13862. This bug was fixed in
glibc-2.21. See
https://sourceware.org/bugzilla/show_bug.cgi?id=13862. The upstream
bug report has a reproducer which reliably reproduces the problem.
I have reported this bug to Debian (#854007), and provided a
backported patch for the glibc-2.19 package included in Debian-8 (0001
-Resize-DTV-if-the-current-DTV-isn-t-big-enough.patch). I have not
tested whether this patch resolves this issue in eglibc-2.19 in Ubuntu
14.04, however the reproducer in the original glibc bug report does
reliably reproduce the problem on Ubuntu 14.04.5 with the latest
glibc6 package installed.
