#36473 [Com]: Foreign Images w/getimagesize() crash Apache2

ID: 36473 Comment by: stitched at mindspring dot com Reported By: punkpuke at terraimpetus dot com Status: Feedback Bug Type: Apache2 related Operating System: Windows XP Pro PHP Version: 4.4.2 New Comment: This also happens with Apache 1.3.33 and 2.0.54 consistently with 4.4.2 on Windows 2000. Will try to get a backtrack but given where and when it's crashing it may not work. Dave Previous Comments: ------------------------------------------------------------------------ [2006-02-24 13:59:44] Peter at ibforen dot de I have had a similar problem with IIS and php.exe: With external urls getimagesize causes an indefinite loop in that function. Using the isapi module php4isapi.dll solves the problem. ------------------------------------------------------------------------ [2006-02-21 23:10:44] mike@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-02-21 20:04:02] punkpuke at terraimpetus dot com I would love to help, however those instructions aren't detailed enough for me to do anything.

I'm sorry, I'm not that smart. :( ------------------------------------------------------------------------ [2006-02-21 13:52:32] mike@php.net Thank you for this bug report.
