Previous Comments: ------------------------------------------------------------------------ [2002-07-24 20:08:03] sniper@php.net This _might_ be fixed already, as the module shutdown order happens now in reverse as they were loaded (might be related). Please try this snapshot: http://snaps.php.net/win32/php4-win32-latest.zip ------------------------------------------------------------------------ [2002-07-24 14:42:08] zimpel@t-online.de This issue still persists in PHP4.2.2 as I recently checked. I can't provide a script to reproduce the problem, because only the startup and immediate shutdown of the sapi module is sufficient as a trigger. I tried to debug the PHP.exe based on php4ts.dll, but the crash isn't reproducible then. I made a small addition to cgi_main.c in order to invoke the shutdown-code: cgi_sapi_module.shutdown(&cgi_sapi_module); I used the 4.2.2 source distribution and build it on NT4/SP6 with MSVC6. The error is still as described below, except it also happens in debug builds now (probably changed preprocessor directives). I only wonder, if the p->pLast is NULL but the rest of the structure is still intact. If I can provide further support (e.g. logs), don't hestitate to ask. -- cu, Holger ------------------------------------------------------------------------ [2002-03-04 00:00:01] php-bugs@lists.php.net No feedback was provided for this bug for over a month, so it is being suspended automatically.

Do you have a script that reproduces this problem (preferably with the CGI version of PHP)? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
