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: [email protected]
Reporter: [email protected]
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

/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 2/71 DPDK:fast-tests / bitmap_autotest OK 0.90s ...
