That... Sucks.
I don't know why we still bundle it. The lib hasn't been updated for 6 years so noone really cares...

Anyway. Nothing we can do really :(

Missed the doc link explaining this: http://www.php.net/recode.installation

very thanks.

Hi,

please also remove the recode.so from PHP extensions.ini file. Took me hours to figure this one out. Without the file being commented out, PHP segfaults on startup.

Best regards
Sebastian
