All right, this is a rough one to report as I only have vagure ideas as to what's going on ... but it really sucks either way. the function call... report($queryusa,$uasusa_trans,$uasusa_style,"User does not have access to any systems",sizeof($uasusa_trans)*2,0,"System Access"); the function function report($query, $tarray,$sarray, $empty_msg,$total,$is_last = 0, $zhead="") The crash the overwrite (I'm convinced it's an overwrite because EIP is 0x00d72f10 and memory is the same value, and a rudimentary jump (albeit confusedly)into msdev vdebug showed something similar) happens at the call to odbc prepare... $sh = odbc_prepare($DBH,$query) or die (odbc_errormsg().$query); the odbc_connect looks like $DBH = odbc_connect($GLOBALS['DSN'],$GLOBALS['DSN_USER'],$GLOBALS['DSN_PW']) or die (odbc_errormsg()); as it stands now I am under a deadline so I can't dig too deep (I have to find a workaround) ,but I'll follow up with any supplemental material I can.. oh, ODBC Driver is Tandem NONStop..

Sigh... I'm not so sure it's with globals anymore, I just knowit's with ODBC I had this problem once before and ended up re-writing and inlining all my code to get it go away. (side note, php cvs build for win2k from php4win project (approaching 4.0.7 release) exhibited the same problem) this particular file is also the only one to crash out of all the php files.. what makes it unique is the rather long subroutine but I've gotten a stack trace and some more information it dies with the following <b>Fatal error</b>: Call to undefined function: () in <b>C:\dev\isis\web\view_ user_info.php</b> on line <b>39</b><br> and it's 0Xc00000005, typically a buffer issue... 01222f10() ODBC32! 1f7d792e() ODBC32! 1f7d7866() PHP4TS! 100026a9() PHP! 00401a43() PHP! 0040207b() KERNEL32! 77e97d08() echo's removed, but assignments left in to give a general idea what's going on...
