--- Comment #14 from Mark Wielaard <m...@klomp.org> --- Very odd. On an almost identical Fedora 40 setup both ./a.out and valgrind -q --tool=massif ./a.out simply return 0 (as they should) for the memchr example. Could you run with valgrind -v and see which architecture cpu flags it detects. Locally I get: Arch and hwcaps: AMD64, LittleEndian, amd64-cx16-lzcnt-rdtscp-sse3-ssse3-avx-avx2-bmi-f16c-rdrand-rdseed-fma -- You are receiving this mail because: You are watching all bug changes.
