# Valgrind issues caused by tip of tree libjpeg-turbo
# https://code.google.com/p/skia/issues/detail?id=4030
# TODO (msarett): Determine if any of these errors relate to jpeg_skip_scanlines() and fix those.
#                 Issue 4 looks like it may.
#                 Some of these errors may be fixed when we switch to Chromium's version of turbo.
#                 If they are not fixed in Chromium's version, they need to be fixed after we switch.
