Ill find out and get that updated if that is the case. CLosing this bug for now as it seems a tertary problem rather than a PHP one. - James ------------------------------------------------------------------------ [2002-09-30 04:32:32] kja@filanet.dk I just tried your latest-cvs-with-curl build and yes that is also working for me. However, the latest non-stable snapshot http://snaps.php.net/win32/php4-win32-latest.zip (dated 20020929) is still failing and I would have thought that was the same code as you tested, or is there just some latency from CVS to the latest non-stable builds? ------------------------------------------------------------------------ [2002-09-28 04:50:41] jmoore@php.net OK just built Debug and Release versions of Curl (Curl-7.9.8) (NON-SSL) and the same of the PHP Extension from the latest CVS and cannot reproduce this bug in the latest versions. The crash no longer happens. Although it is reproduceable with PHP-4.2.3 which was downloadable from PHP.net. You can download the version I tested this with (Only got php_curl.dll & libcurl.dll accompanying it) from http://www.phpuk.org/~james/latest-cvs-with-curl.zip. Please let me know if the problem persists with you in this build. - James ------------------------------------------------------------------------ [2002-09-25 04:19:11] jmoore@php.net Ill have a look at this on friday and see if I can reproduce this and get a stack trace then hopefully fix it. If anyone wants a play before hand then they are welcome to. - James ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
