From: dietrich dot ayala at foundstone dot com Operating system: windows 2000 PHP version: 4.3.3 PHP Bug Type: Reproducible crash Bug description: fastcgi + pfsockopen = crash
Description: ------------ first time loading the reproduction script works fine. subsequent reloads will first cause php.exe to crash (The instruction at "0x100108b4" referenced memory at "0x00000000". The memory could not be "read".), then once I hit OK on that alert, I'll get a "Server Error, unable to connect to fastcgi server." error in the browser. We've found that this error text is in the FastCGI source. It looks like maybe php crashes, then fastcgi attempts to access a php thread that has gone bye-bye, and throws that error. So there may be 2 issues: what's causing the original php crash, and then the fastcgi problem. Here's how to repro: - environment: win2k, IIS, FastCGI, PHP 4.3.2/.3 (I repro'd w/ both) - set up a test script, such as a phpinfo script - configure the repro script to hit your host, port, path_to_test_script and load it, then hit refresh (sometimes, I'll have to restart w3svc to be able to repro the bug) notes: - this does not occur if using fsockopen, only with pfsockopen - i could not reproduce this with windows XP, only windows 2000 (both server and professional) Reproduce code: --------------- http://dietrich.ganx4.com/phpbug_iis.phps Expected result: ---------------- it should output the URL it's attempting to connect to. Actual result: -------------- first time loading the reproduction script works fine. subsequent reloads will first cause php.exe to crash (The instruction at "0x100108b4" referenced memory at "0x00000000". The memory could not be "read".), then once I hit OK on that alert, I'll get a "Server Error, unable to connect to fastcgi server." error in the browser. -- Edit bug report at http://bugs.php.net/?id=25597&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25597&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25597&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25597&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25597&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25597&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25597&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25597&r=support Expected behavior: http://bugs.php.net/fix.php?id=25597&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25597&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25597&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25597&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25597&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25597&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25597&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25597&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25597&r=float
