Description

When initializing XalanC with :

XalanTransformer::initialize()

a math error occured. We defined "_matherr" on our projects to correct some common errors. Info on _matherr could be found here : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt__matherr.asp

The problem really occurs when calling :

DoubleSupport::initialize( theManager ) in PlatformSupportInit::initialise( theManager )

This is the most accurate location I could give based on my call-stack.

The struct exception (argument receive in _matherr ) tell us that :

you are calling "sqrt" with a negative value (-2.00999999999...8)

If we correct the error by assigning retval with 0, XalanC do not initialize correctly.
