Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better.

All other algorithms seem to work except MD5. NOTE: This appears to possibly be related to bug #30983 which is closed (and I could not touch it). In that bug, it was claimed to 'not imply a bug in PHP itself'. This may be true, however similar tests against the Mhash library itself using C code function as expected. I ran the same test against the Mhash library using the following C code located here: http://www.5dollarwhitebox.org/tmp/mhash_test.c You must install the Mhash library obviously, then compile and run the test file: [EMAIL PROTECTED] ~]$ gcc -lmhash -o mhash_test mhash_test.c [EMAIL PROTECTED] ~]$ ./mhash_test The issue exists on Rhel3 i386/x86_64, but does *not* exist on Rhel4.. and I am using Mhash-0.9.9 Reproduce code: --------------- PHP Code: <?php $input = "PassW0rd"; print "clear text input: " . $input . "\n"; $tmp_hash_name = mhash_get_hash_name(MHASH_MD5); print "hash name: " . $tmp_hash_name . "\n"; print "hash follows: "; print bin2hex(mhash(MHASH_MD5, $input)) . "\n"; ?> Expected result: ---------------- Expected PHP Output: [EMAIL PROTECTED] ~]$ php mhash_test.php clear text input: PassW0rd hash name: MD5 hash follows: 298cde70c32a57b84d0a546fedbb2596 Actual result: -------------- Actual PHP Output: [EMAIL PROTECTED] ~/]$ php mhash_test.php clear text input: PassW0rd hash name: MD5 hash follows: Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41545&edit=1
