Description:
------------
description in http://bugs.php.net/bug.php?id=27759 describes the problem well. there is also the same problem with bcsub. its reported again because the bug is still present in latest cvs build.

Reproduce code:
---------------
PEAR`s Benchmark_Timer::getProfiling():
//... this is part of loop - first settings of parameters are empty, and apache throws exception right away
$diff  = bcsub($time, $temp, 6);
$total = bcadd($total, $diff, 6);  
//...

Actual result:
--------------
apache exception ['memory cannot be read']

some more precise info
in above example: $total = $temp = 0

i tried other settings:
$total = $temp = '0' still caused error.
$total = $temp = '0.0' worked fine

hope this info helps - it looks like some kind of variable type conversion problems

I'm still experiencing this issue, exactly as described, using a build from this mornings CVS.

I'm using Apache2 and Windows 2k Pro, with PHP compiled as a module, and lib_mysql and lib_mysqli in use.

I'm available for any tests that might be necessary, though I'm not comfortable compiling PHP on Windows.
