Without native (MEMPROF_PROFILE=dump_on_limit) it works ok

php -dextension=memprof.so -i | fgrep memp
memprof
memprof support => enabled
memprof version => 3.0.0
memprof native malloc support => Yes
memprof.output_dir => /tmp => /tmp

phpinfo()
PHP Version => 7.4.10

Hi @denis-kopelevich

Thank you for this report.
