Valgrind suppression file for FontForge built with Pango

valgrind_ff_pango.supp

# The below suppressions suppress just about every entry that pango 
# libraries could have contributed to.  This is likely excessive... ;)
#
# We make good use of the wildcarding features of Valgrind.  By using 
# wildcarded library object filenames we can hope this source is 
# portable to more systems.

# On one tested system (Ubuntu 14.04), these libraries are:
#     /usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so.0.3600.3
#     /usr/lib/x86_64-linux-gnu/libpangoxft-1.0.so.0.3600.3

#     /usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0.3600.3

# On the tested system (Fedora 20), these libraries are:
#     /usr/lib64/libpango-1.0.so.0.3600.1
