flow: Promoted
'trunk' (22bf185b75f0) to 'feature/valgrind'.
#
# This is a valgrind suppression file that should be used when using valgrind.
#
# Here's an example of running valgrind:
#
# cd python/dist/src
# valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp \
# ./python -E -tt ./Lib/test/regrtest.py -u bsddb,network
#
# You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER
# to use the preferred suppressions with Py_ADDRESS_IN_RANGE.
#
# If you do not want to recompile Python, you can uncomment
# suppressions for PyObject_Free and PyObject_Realloc.
#
# See Misc/README.valgrind for more information.
# all tool names: Addrcheck,Memcheck,cachegrind,helgrind,massif
