This is because memmove() can call __memcpy_chk(), which triggers the
false positive in valgrind.
It probably affects other places too, but for us it's sufficient to
restrict the valgrind suppression to calls from inet_pton(). This
suppression will probably break with LTO enabled.

# IMPORTANT: these suppressions strongly depend on the used library version.
|
|
# They probably don't work out-of-the-box on anything but Fedora, where they
|
|
# are mainly tested.
|
|
#
|
|
# Make sure to install debug information, otherwise the suppression trace might
|
|
# not match. On Fedora, try 'dnf debuginfo-install glib2'.
