To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2011-06-12 03:18:48] crrodriguez at opensuse dot org Description: ------------ Hi: php_zval_filter_recursive segfaults once in a while, with the following backtrace Test script: --------------- Program terminated with signal 11, Segmentation fault. #0 0x00007fb81e3a58a2 in php_zval_filter_recursive (value=0x7fb823d86768, filter=140736822777868, flags=140736822777848, options=0x7fb823d86790, copy=<value optimized out>, charset=0x0) at /usr/src/debug/php-5.3.6.201106102115/ext/filter/filter.c:524 529 if (Z_TYPE_PP(element) == IS_ARRAY) { (gdb) bt full #0 0x00007fb81e3a58a2 in php_zval_filter_recursive (value=0x7fb823d86768, filter=140736822777868, flags=140736822777848, options=0x7fb823d86790, copy=<value optimized out>, charset=0x0) at /usr/src/debug/php-5.3.6.201106102115/ext/filter/filter.c:524 element = 0x0 pos = 0x7fb823d86790 #1 0x0000000000000000 in ??
