#28493 [NEW]: php_imap.dll (and others) load failure on Windows 98

From: sanondysie at tc17 dot com Operating system: Windows 98 PHP version: 4.3.6 PHP Bug Type: Dynamic loading Bug description: php_imap.dll (and others) load failure on Windows 98 Description: ------------ This problem seems to present itself only on Win98 systems (possibly on other Win9x as well). I have tested this on an almost-out-of-the-box Win98 system as well a Win98 system with all the latest MS patches including MSIE 6.0 SP1; symptoms are identical. Systems ARE able to use the curl extension; systems ARE able to use the gd2 extension. Systems are NOT able to use the IMAP extension. There are many Usenet messages about this problem as well; there doesn't seem to be any solution that has been shown to work. Symptoms can be demonstrated by either: 1) configure imap with php.ini, or 2) <?php dl ("php_imap.dll"); ?> The error message returned is something like: Unable to load dynamic library ...php_imap.dll - A device attached to the system is not functioning. A little bit more analysis with \windows\system\regsvr32 gives: LoadLibrary ...php_imap.dll failed GetLastError returns 0x0000001f. The 0x1f (31) error maps to "device attached to the system is not functioning" is apparently a catch-all for errors for which the original programmers could not be bothered supplying details. However, this is NOT the error shown for missing DLLs (that's a 0x4xx error); Analysis with scanbin (available from: http://www.bellamyjc.net/) seems to show that there are two presumed problems with calls: KERNEL32: LoadLibrarya KERNEL32: GetProcAddress The conclusion seems to be that the problem is inherent in php_imap.dll itself, possibly the way in which is is built; possibly some subtle API interface problem (with KERNEL32), a difference between Win9x and WinNT kernels? -- Edit bug report at http://bugs.php.net/?id=28493&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28493&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28493&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28493&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28493&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28493&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28493&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28493&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28493&r=support Expected behavior: http://bugs.php.net/fix.php?id=28493&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28493&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28493&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28493&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28493&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28493&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28493&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28493&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28493&r=float
