This affects all the bcmath functions and happens when either of the first two arguments evaluates to zero (this means 0, '0', and ''). I have the same setup as the original submitter. ------------------------------------------------------------------------ [2004-03-29 16:29:14] pollita@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2004-03-29 15:43:37] patrick at rap-x dot com Description: ------------ The following code causes PHP5 RC1 (module)/ WINXP / Apache2 to crash. The same code doesn't cause a crash on PHP 4.3.4 / WINXP/ IIS (CGI) Fault discovered by using PEAR :: Benchmark Workaround is to mess around line 230ish in pear Timer.php so that the bcadd is not called. Reproduce code: --------------- $total = "0"; $diff = ""; bcadd($total, $diff, 6); Expected result: ---------------- n/a Actual result: -------------- Apache2 crashes Windows Event Log records: Faulting application Apache.exe, version 2.0.49.0, faulting module php5ts.dll, version 5.0.0.0, fault address 0x0003c773.
