I was trying to restore object data from session, and php segfaults, when i do session_start for the seccond time. I guess it's unserialize's fault. Here is a script causing the problem: <? class Test { var $a; } session_start(); var_dump($_SESSION); echo "session started"; $x = new Test; session_register('x'); var_dump($_SESSION); ?> session data looks like this: x|O:4:"test":1:{s:1:"a";N;} Here is a gdb backtrace (gdb) bt #0 0x8170b51 in ??
