 Operating System: win32 only - Windows 2003 SP2
 PHP Version:      5.2.11
 New Comment:

For what I see in the crashlog, it uses ISAPI. To use PHP with IIS, the
recommended way is FastCGI (nts build, non thread safe).

If you are using it only in the command line, please use the NTS (non
thread safe) as well.

We also need a script to reproduce the crash.

Same problem with 5.2.11

Tested with 5.2.11, 5.2.10, 5.2.6

I thought it was due to mssql ext. so I've switched to sqlsrv and still
go the crash.

loaded extension are:
php_curl.dll
php_mcrypt.dll
php_mysql.dll
php_sockets.dll
php_zip.dll
php_sqlsrv_ts.dll

I'm not using it in a web server, it's as a command line using the
php.exe.

I've got the same proble with 5.2.6 and trying with 5.2.11RC3...

ISAPI is deprecated and not maintained anymore. Please try the same
script using the FastCGI interface instead (works with IIS5/6/7).
