It's a bug in valgrind, in coregrind/m_initimg/initimg-linux.c: setup_client_stack()

Both AT_DCACHEBSIZE and AT_HWCAP2 are missing

Fix the DCACHEBSIZE issue

The attached patch for the current valgrind repository ( svn co svn://svn.valgrind.org/valgrind/trunk valgrind ) appears to fix the issue with the AT_DCACHEBSIZE not being handled. In testing this, I noticed there is also the value of AT_SYSINFO_EHDR that is not being printed. Anton mentioned that HWCAP2 is missing. I will work on addressing these issues. Not sure if the AT_DCACHEBSIZE is sufficient to get you past the current issue or not but wanted to post it for testing in the hope that it is sufficient for the moment.

The upstream Valgrind code has been updated with the needed fix.

The fix will be available in the next Valgrind release.

Up to the Distro if they want to add the attached patch to their next release or not.

I downloaded the build and tested it. It seems to work fine. Will mark it as Tested.

Hello bugproxy, or anyone else affected,

Accepted valgrind into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/valgrind/1:3.10.1-1ubuntu3~14.04 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 add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and 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!

  * Merge with Debian; remaining changes:
    - Remove valgrind-mpi package from Ubuntu and any references to it, as
      mpi-default-dev is in universe for the time being.
    - Lower over-inflated valgrind-dbg Recommends to Suggests instead.
    - Don't strip vgpreload* on ARM; this results in unusable stack traces
      without valgrind-dbg.
    - Configure with --enable-only64bit on AArch64.
