Valgrind suppression file for FontForge built with Python 3

valgrind_ff_p3.supp

# This file for FontForge built with Python 3
#
# The below suppressions suppress just about every entry that Python 
# could have contributed to.  This is likely excessive... ;)
#
# We make good use of the wildcarding features of Valgrind.  By using
# wildcarded function names we can cover more cases with just one entry.
# And by using wildcarded library object filenames we can hope this 
# source is portable to more systems.

# On the tested system (Fedora 20), these libraries are:
#       /usr/lib64/libgobject-2.0.so.0.3800.2
#       /usr/lib64/libpython3.3m.so.1.0
#       /usr/lib64/ld-2.18.so

# On one tested system (Ubuntu 14.04), these libraries are:
#       /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0.4000.0
#       /usr/lib/x86_64-linux-gnu/libpython3.4m.so.1.0
#       /lib/x86_64-linux-gnu/ld-2.19.so

but for less output you might want
