Yes. It is a compiler bug. This patch set is NOT introducing this.
Fixed same on legacy build with arm64 . If you are using < 4.8.6 compiler
For meson, this patched needs to be ported to meson

commit f3af3e44a444cdfe3fa7b3e2c042be351401eb23

mk: disable OcteonTx for buggy compilers only on arm64
Disable octeontx for gcc 4.8.5 as the compiler is emitting "internal
compiler error" for aarch64. The GCC "internal compiler error" was
observed only for arm64 architecture so disable the PMD only
for arm64.
