--- Comment #2 from Henning Baldersheim <balder at yahooinc dot com> ---
This is an even bigger issue with gcc 13. Then it only requires -march=haswell

Works:
c++ -Wall -Wextra -O3 -march=ivybridge test.cpp && ./a.out

Fails:
c++ -Wall -Wextra -O3 -march=haswell test.cpp && ./a.out
a.out: test.cpp:23: void assert_stats(size_t, size_t, size_t, size_t, Stats):
Assertion `exp_dead == stats._dead' failed.

gcc version:
gcc -v
Using built-in specs.
