The e1000 PMD stopped working under Ubuntu-24.04 (using gcc-13) when

The crash is linked to the use of gcc-13: under Ubuntu-24.04 testpmd
compiled with gcc-11 from the same DPDK tree works as expected.
The perfect solution would be for someone to investigate why the
PMD crashes. However, this depends on Maintainer availability.
Hi,
can you test with [1]. It's still a workaround while we investigate more,
but a less severe one!
Hello,
Thanks for the quick turnaround.
The compilation is ongoing. I will post ASAP, when the test has run.
