This bug was fixed in the package mesa - 19.0.8-0ubuntu0~18.04.2
---------------
mesa (19.0.8-0ubuntu0~18.04.2) bionic; urgency=medium
* i965-revert-enabling-softpin.diff: Dropped, unnecessary by now and
broke Ice Lake which needs softpin. (LP: #1815172)
* rules: Force -DNDEBUG, meson < 0.47 is buggy and doesn't set it even
if we have b_ndebug=true. (LP: #1841412)

Fix Released
Bug description:
[Impact]
Mesa is now built with meson, and it turns out that meson < 0.47.0 (commit
7c4736d27f4c5d7 to be exact) doesn't handle command line options properly which
means that -Db_ndebug=true didn't have any effect when mesa is built on bionic.
This means that some asserts are enabled, and at least nouveau is affected.
[Test case]
chech the build log that -DNDEBUG is passed
[Regression potential]
none really, it just adds a build flag which should've been there
