#19301 [NEW]: curl_exec crashes

From: honza@honza.info Operating system: Windows XP Professional CZ PHP version: 4.2.3 PHP Bug Type: Reproducible crash Bug description: curl_exec crashes Hello, I'm a newbie to PHP, so it may be something wrong on my side. But I checked the problem, reproduced it many times so here I send it. I replicated the problem many times in Windows XP Professional CZ, which I use as my operating system. I also have a separate instalation of Windows 2000 Professional CZ SP2, which I use for my full time job, and I replicated the problem there as well. While there is a lot of software installed on my WinXP system, the Win2000 system was completely clean (I was reinstalling the system for new project), so there was just Win2000 Pro CZ SP2 and PHP 4.2.3 on the system, nothing more. The only difference was the crash dialog it produced: under Win2k it was the dialog "Error in program: php.exe generated errors and so Windows closed it. It is neccessary to restart the program. Generating error protocol. OK button", while WinXP give the dialog of "Error occured in php.exe application and it is necessary to close it. We are apologizing for caused problems. ... Report the problem to Microsoft ... Send the report button and Don't send button" (please note that I use the Czech localization of Windows and here I translated back the messages from the dialogs in Czech language in my Windows into English, so the original texts may differ). What I did: I copied the example featured at curl_init function documentation to a file, and changed the url, so it is now: <?php $ch = curl_init ("http://www.ebay.com"); $fp = fopen ("output/result.txt", "w"); curl_setopt ($ch, CURLOPT_FILE, $fp); curl_setopt ($ch, CURLOPT_HEADER, 0); curl_exec ($ch); curl_close ($ch); fclose ($fp); ?> This simple code crashes with dialogs mentioned above. It always crashes, I had no successfull run. Note 1: Commenting the lines (using //) in the source I came to the result that the crashing function is curl_exec(). Other functions work OK. If I comment only the line with curl_exec() and nothing more, the script will successfully run. Note 2: I uncommented the php_curl.dll in php.ini, the extension is allowed (I tried the script with the extension left commented, and then it fails on line with curl_init() function). Note 3: The extension_dir in php.ini is set to proper location. I tried it set to wrong dir and it produced errors on curl_init() function. Note 4: It crashes no matter if it is run from DOS-prompt using php.exe, php-cli.exe or via web server (IIS). Note 5: When run through IIS the "output" directory has the write allowed, and the file "result.txt" is created. As curl_exec fails, the file "result.txt" is left of 0 lenght. Note 6: Although I didn't see it mentioned in the install documentation for Windows, before getting into this crashing problem I got a report that "libeay32.dll cannot be loaded". Of course adding php-install-dir/dlls into PATH env variable helped. I think it would be good to add this into install documentation. OK, that's all for now. Tomorrow I'll try it on different machines (although they will all be Windows, but simply up-to-date I tried it only on one computer, just different systems) and I'll report if it behaves the same in there as well.
