            Bug ID: 1967
           Summary: [dpdk-26.07] ABI testing dpdk26.07+dpdk25.11
                    meson_tests/test_fasts vdev_autotest and
                    devargs_autotest both failed
           Product: DPDK
           Version: 26.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: yux.jiang@intel.com
  Target Milestone: ---

Environment
-----------
DPDK version:  
[DPDK 26.07rc3] 


Steps to reproduce
------------------

1, Build latest dpdk(dpdk26.07rc3)
cd dpdk
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Dlibdir=lib -Dc_args=-DRTE_BUILD_SHARED_LIB
--default-library=shared x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf /root/tmp/dpdk_share_lib /root/shared_lib_dpdk
DESTDIR=/root/tmp/dpdk_share_lib ninja -C x86_64-native-linuxapp-gcc -j 110
install
mv /root/tmp/dpdk_share_lib/usr/local/lib /root/shared_lib_dpdk
cat /root/.bashrc | grep LD_LIBRARY_PATH
sed -i 's#export LD_LIBRARY_PATH=.*#export
LD_LIBRARY_PATH=/root/shared_lib_dpdk#g' /root/.bashrc

2, copy LTS(dpdk25.11) dpdk_abi.tar.gz and build LTS dpdk
tar zxf /tmp/dpdk_abi.tar.gz -C ~
cd ~/dpdk/
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Dlibdir=lib -Dc_args=-DRTE_BUILD_SHARED_LIB
--default-library=shared x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf x86_64-native-linuxapp-gcc/lib
rm -rf x86_64-native-linuxapp-gcc/drivers

3, do meson test
meson test -C x86_64-native-linuxapp-gcc --suite DPDK:fast-tests
devargs_autotest vdev_autotest -t 24 --num-processes 20  --test-args '-l 1-8 -d
/root/shared_lib_dpdk' 

Show the output from the previous commands.

RTE>>vdev_autotest
== test vdev bus ==
Segmentation fault (core dumped)


Expected Result
---------------
Test OK


Is this issue a regression: Y
-----------------------------
devargs_autotest bad commit: d03dbd4003 bus: support multiple probe
vdev_autotest bad commit: 89127f66f5 bus: consolidate device lookup


Need fix or not? pls confirm
