Behdad Esfahbod 447323b85a Better fix for -Wcast-align errors 2019-01-22 12:50:12 +01:00

Behdad Esfahbod 8d05bf7dc0 Fix cast-align error
If compiler doesn't inline StructAtOffset, this was an error since we
only disable cast-align at call-site.  So, move the cast out.

Philip Withnall ffde3c9f9e hb-font: Fix a potentially undefined use of memcmp() (#413)
While it’s fine to call memcmp(x, 0, 0) in practice, the C99 standard
explicitly says that this is not allowed: even if the length is zero,
the pointer arguments must be valid.
