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@dpdk.org
Reporter: drc@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
