ROFL -----Original Message----- From: twitch [mailto:[EMAIL PROTECTED] Sent: Friday, July 18, 2003 4:56 AM To: [EMAIL PROTECTED] Subject: [PHP-INST] Debug Assertion deep inside php_execute_script() on an SAPI. Hi, I am trying to get a PHP 4.3.2 SAPI working on Windows. I am using Visual Studio 6.0 and am using the Debug Release (php4ts_debug.dll). I can successfully get the CLI (phpCLI.c) version of PHP working just fine using the same linking instructions as I do for my SAPI program. My SAPI is heavily based off the thttpd sample SAPI. Right now I am getting a "Microsoft Visual C++ Debug Library" assertion: --- Begin Dialog Contents --- Debug Assertion Failed! Program: c:\work\out\bin\phpServerHarness.exe File: fdopen.c Line: 54 Expression: _osfile(filedes) & FOPEN For information on how your program can cause an asserion failure, see the Visual C++ documentation on asserts.

I don't really know "what" they're trying to do from then on, but it goes through a few functions (see stack) and ends up at that assert. The arguments to php_open_wrapper_as_file look correct (valid paths). I know this is a long shot, but if anyone can help me -- give me some kind of pointer on where or what to look for -- libraries, languages, ThreadSafe versus not ThreadSafe -- I'd really appreciate it. I've been stumped for days. I don't really know how to get more information on the code I'm looking at. thanks! twitch -- PHP Install Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP Install Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
