6b89650418f adds
+# Strict-aliasing rules are violated by uint8_t[] to context size casts.
+CFLAGS +=3D -fno-strict-aliasing
to app/test/meson.build.

This flag applies to all tests, not just the broken RTE graph tests (or SUT=
?).

Passing this flag to the compiler will prevent any functional tests (of any
component) from detecting any aliasing-related bugs found in code located in
SUT header files.

RTE graph should be fixed, rather than a whole-sale application of this
work-around to DPDK test suite.

In additional, reducing the level of compiler optimization will make the pe=
rf
test less relevant.
