Bug #16859 Updated: session_decode gives SEGV in PHP 4.2.0
ID: 16859 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Session related Operating System: Solaris 2.6 (5.6) PHP Version: 4.2.0 New Comment: As an explanation to the backtrace I posted: The backslashes that appear before some of the double quotes in the backtrace are due to gdb. The file that is read (and the string that's processed) do _not_ contain the backslash. The variable ses_login is the first of the session variables that are stored as part of the session data. The backtrace says that it's dying in session.c, line 290. This is in function php_set_session_var(), at the point where it's trying to call zend_set_hash_symbol(). The PHP setting register_globals is set to On in both the local and master contexts. The script that causes this error is calling session_decode without having called any kind of session_start or session_name beforehand. (Again, this works as I expected it to in 4.1.2; the SEGV is in 4.2.0).

[2002-04-26 13:20:03] [EMAIL PROTECTED] session_decode ($str) gives SEGV with PHP 4.2.0 and Apache 1.3.24. Worked fine with PHP 4.1.2; I just built 4.2.0 with the same configure params and same Apache as I had with 4.1.2, and the same script gives the problem. I have verified that the argument to session_decode ($str) is not null, etc. Basically, my script is reading the $str out of several sess_* files and dumping the contents for each one. There was a session_decode SEGV bug that was reported as fixed and closed in 4.0.1 pl2, so maybe the same bug is back. Thanks to all. -- Edit this bug report at http://bugs.php.net/?id=16859edit=1
