            Bug ID: 1197
           Summary: Segmentation fault running acl_autotest when built
                    with gcc 11 and -O3 on ppc64le
           Product: DPDK
           Version: 23.03
          Hardware: POWER
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev at dpdk.org
          Reporter: drc at linux.vnet.ibm.com
  Target Milestone: ---

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            
1.27s   killed by signal 11 SIGSEGV
>>> MALLOC_PERTURB_=139 DPDK_TEST=acl_autotest
>>> /home/drc/src/dpdk/build/app/test/dpdk-test --no-huge -m 2048
>>> --file-prefix=acl_autotest

Building the same code with -O2 works correctly:

$ meson -Doptimization=2 build && meson test -C build --suite DPDK:fast-tests
...
[2397/2397] Linking target app/test/dpdk-test
 1/71 DPDK:fast-tests / acl_autotest                        OK              
2.72s
