Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgHello Harald Welte, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/4915
to look at the new patch set (#2).
sanitize build: ensure uint16/32 alignment in gtpie_test and in46a_test
Fixes sanitize build failures:
