[Bug 1028038] Re: sscanf always calls realloc/causes deadlock in google-perftools

[Clint Byrum]

Hello James, or anyone else affected,

Accepted eglibc into precise-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/eglibc/2.15-0ubuntu10.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Changed in: eglibc (Ubuntu Precise)
       Status: Triaged => Fix Committed

** Tags added: verification-needed

Title:
  sscanf always calls realloc/causes deadlock in google-perftools

Status in “eglibc” package in Ubuntu:
  Fix Released
Status in “eglibc” source package in Precise:
  Fix Committed

Bug description:
  SRU Justification:

  [Impact]
  When using google-perftools eglibc causes a deadlock.

  [Development Fix]
  This is fixed in quantal.

  [Stable Fix]
  A fix can be backported from quantal into precise.

  [Test Case]
  Run google-perftools.

  [Regression Potential]
  Patch introduces changes in stdio-common/vfscanf.c.

  --

  This is currently causing a deadlock in the google-perftools testing.

  The fix has been committed to glibc 2.16 - http://cygwin.com/ml/libc-
  alpha/2012-01/msg00026.html

  It would be great if either glibc could be upgraded to 2.16 or this
  patch applied to the version in quantal.

  I have verified locally that this resolves the deadlock issue in
  google-perftools.
