[Bug 1567219] Re: Valgrind does not support compressed debug info

[Launchpad Bug Tracker]

This bug was fixed in the package valgrind -
1:3.12.0~svn20160714-1ubuntu2

---------------
valgrind (1:3.12.0~svn20160714-1ubuntu2) yakkety; urgency=medium

  * Cherry-pick upstream patch to fix assertions on arm. LP: #1612429

valgrind (1:3.12.0~svn20160714-1ubuntu1) yakkety; urgency=medium

  * Merge with Debian (LP: #1567219) remaining changes:
    - 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.

  * Reintroduce universe/valgrind-mpi package, as archive reorg is done.
  * Drop s390x patches, applied upstream.

valgrind (1:3.12.0~svn20160714-1) unstable; urgency=medium

  * New upstream snapshot release
    - Add support for compressed debuginfo (Closes: #810295)
  * Drop MIPS patches (merged/fixed upstream)
  * Refresh patches
  * Add smoke test for autopkgtest
    Thanks to dann frazier for the patch (Closes: #819813)
  * Update 07_fix-spelling-in-binary.patch
  * Update Standards-Version to 3.9.8 (no changes needed)
  * Update Vcs-* URLs

  It seems that some Ubuntu debug packages are built with compressed debug info, which is not supported by Valgrind.  In particular I've seen that this even applies to the dynamic loader (when libc6-dbg is installed):

  Note that this issue should apply to all platforms.  It has already been reported for upstream Valgrind, and a patch has been proposed:
