Can you please verify whether removing the free() in the function body will fix it (in http://lxr.php.net/xref/PHP_MASTER/Zend/zend_compile.c#100)? [And probably cause a mem leak instead] If that's the issue, I'll prepare a proper patch. ------------------------------------------------------------------------ [2016-01-19 19:04:14] mike@php.net Description: ------------ a75c195000 (class constant visibility patch) seems to cause problems, when extensions register constants on interfaces; no problems with PHP-7.0 It's a bit tricky to reproduce, but building e.g. https://github.com/m6w6/ext-pq into PHP-master may trigger the crash; see https://gist.github.com/m6w6/58dd72c02344487d6346#file-valgrind-log and https://travis-ci.org/m6w6/ext-pq/builds/103342033 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71413&edit=1
