segmentation fault when passing arguments by reference or importing global variables

Dear All: Im having some weird problems here. We're working on a big project, based on PHP and we found that some code that used to work, is doing very strange things. Im getting segfaults in some parts of the code, for example: function XXX(&$databaseConnection, $xxx) { or global $xxx; At first, I was getting segfaults with very little info. After I installed php-mmturck, the file, line and opcode where the error happen is reported in apache error log: [4577] MMCACHE: PHP crashed on opline 1 of XXX() at /var/www/xxx/XXX.class.php:58 [Mon Feb 21 15:16:02 2005] [notice] child pid 4577 exit signal Segmentation fault (11) Line 58 has: function XXX(&$databaseConnection, $_xxx) { Im using PHP 4.3.10-2 (debian gnu/linux testing) but I can recompile it or test another version, if you think it's important.
