Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. For Windows: http://windows.php.net/snapshots/ Thank you for the report, and for helping us make PHP better. hmm, I will trigger a E_COMPILER_ERROR while in this situation, since it doesn't make sense for a no-string method name. Dmitry, you maybe want to review this fix. thanks :) Previous Comments: ------------------------------------------------------------------------ [2011-12-28 06:45:47] [email protected] Automatic comment from SVN on behalf of laruence Revision: http://svn.php.net/viewvc/?view=revision&revision=321458 Log: Fix #60613 (Segmentation fault with $cls->{expr}() syntax) #now the behavior is like 5.3, a COMPILER_ERROR will be triggered ------------------------------------------------------------------------ [2011-12-28 06:14:39] [email protected] dmitry, I have a quick look at this, since due to cache mechanism, I have not gat familiar with this area. it is better if you can have a look at this.
