#

# 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 ./Lib/test/regrtest.py -u gui,network

#

# You must edit Objects/obmalloc.c and uncomment Py_USING_MEMORY_DEBUGGER

# to use the preferred suppressions with 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
