[Bug 1512622] Re: Valgrind suppressions don't work on 64-bit systems

 

ok, I see that this file needs some updates from the python2.7 package.

Please could you point out what you would expect to be different from
the 32bit version? The referenced commit doesn't change anything for
64bit, and the changes are already in the python-defaults package.

Title:
  Valgrind suppressions don't work on 64-bit systems

Status in python-defaults package in Ubuntu:
  Incomplete

Bug description:
  Hello!

  The Python package helpfully ships /usr/lib/valgrind/python.supp,
  which is basically the upstream Valgrind suppressions file with some
  suppressions uncommented so they work on standard Python builds.

  Unfortunately those suppressions are tailored for 32-bit systems and
  therefore do not suppress false positive errors in
  PyObject_Free/PyObject_Realloc.

  See upstream bug http://bugs.python.org/issue12612 and upstream commit
  https://github.com/python/cpython/commit/9264faed068b87888a4605ce36bfc9d158515c42
  for the changes you need to do.
