#38393 [Opn->Fbk]: Segmentation Fault when using curl_close in an object context

ID: 38393 Updated by: tony2001@php.net Reported By: asubstitute at gmail dot com -Status: Open +Status: Feedback Bug Type: cURL related Operating System: RHEL4 PHP Version: 5.1.4 New Comment: Does it work if you build it without MySQL support? Previous Comments: ------------------------------------------------------------------------ [2006-08-09 10:32:57] asubstitute at gmail dot com Look in my inital post, see I tried the snapshot code too. (RIght before I submitted this) The procedural code above works only for HTTP urls. HTTPS cause a segfault (though both protocols make the OOP version die) I can run curl from the command line, and it works fine. Indicating it is unlikely to be a libcurl issue.
