# 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
