<pre class="bz_comment_text">Building DPDK with gcc 11 (and later versions) on a ppc64le system with RHEL
8.7 produces a segmentation fault when running the acl_autotest:
$ meson build && meson test -C build --suite DPDK:fast-tests
...
[2397/2397] Linking target app/test/dpdk-test
1/71 DPDK:fast-tests / acl_autotest FAIL

>>> /home/drc/src/dpdk/build/app/test/dpdk-test --no-huge -m 2048

Building the same code with -O2 works correctly:
$ meson -Doptimization=2 build && meson test -C build --suite DPDK:fast-tests
