Bug #66412 [NEW]: readline_clear_history() with libedit causes segfault after #65714

From: php at 0x7f dot us Operating system: OS X 10.9.1 PHP version: 5.5.7 Package: Readline related Bug Type: Bug Bug description:readline_clear_history() with libedit causes segfault after #65714 Description: ------------ Since PHP 5.5.7, calling readline_clear_history() segfaults. PHP 5.5.7 (installed via Homebrew) OS X 10.9 And whatever libedit version ships with OS X 10.9 (Mavericks). From the readline.h file: /* $NetBSD: readline.h,v 1.33 2012/05/15 17:30:04 christos Exp $ */ Note that this is over 11 years newer than the header comment in the SourceForge project linked from the readline ext readme (http://sourceforge.net/projects/libedit/) /* $NetBSD: readline.h,v 1.1 2001/01/05 21:15:50 jdolecek Exp $ */ This version of libedit seems to actually be maintained, I imagine it is more like what is available on OS X: http://www.thrysoee.dk/editline Reverting b8d88bf (a fix for #65714) fixes the segfault.
