Failed to copy zfunc

[rlerdorf]

Was looking at Wordpress both with PHP 7.1 and 7.2 and I got a bunch of these:

0 get_option /var/www/wordpress/wp-includes/option.php:93
1 <main> <internal>:-1
copy_proc_mem: Bad address; raddr=0x100000001 size=128
dump_trace: Failed to copy zfunc

0 translate /var/www/wordpress/wp-includes/l10n.php:134
copy_proc_mem: Bad address; raddr=0x100000006 size=128
dump_trace: Failed to copy zfunc

0 date_i18n /var/www/wordpress/wp-includes/functions.php:103
1 <main> <internal>:-1
2 <main> <internal>:-1
copy_proc_mem: Bad address; raddr=0x40808820000005a size=128
dump_trace: Failed to copy zfunc

Less of them with opcache off, but still some:

0 mysqli_fetch_object <internal>:-1
1 get_object_vars <internal>:-1
2 wp_cache_add /var/www/wordpress/wp-includes/cache.php:30
3 maybe_unserialize /var/www/wordpress/wp-includes/functions.php:330
4 get_metadata /var/www/wordpress/wp-includes/meta.php:510
copy_proc_mem: Bad address; raddr=0x100000001 size=128
dump_trace: Failed to copy zfunc

Theoretically --pause-process will reduce these at the cost of slowing down the target process. I haven't tested that feature much. #17 may also reduce copy failures. Closing this for now.
