Hi,

we are trying to use a custom action to work on an XML document and then XSL transform it.  
The Action is a .NET one written in c# on VS2005. When the action is executed and System.Xml.Xsl.XslCompiledTransform's Load-method is called FinalBuilder Terminates.  
Even during debugging FinalBuilder exits. The last output during debug is:"The program '[2760] FinalBuilder4.exe: Managed' has exited with code -1073741819 (0xc0000005).".

Investigating this i found articles describing a problem of floating point operations of MS-code-based XslCompiledTransform when called from Borland/VCL based applications.  
I guess FB is written in Delphi. We had similar problems in our software that was mixing Delph and MS/C++ modules. It just terminated.  
The issue seems to be wether floating point exceptions should be masked or not. Borland doesn't.

Could you please check if this might cause the Problem we currently have with the custom action?   
The Borland link proposes a change that would need to be applied in the calling application. Would that be an option to add to FinalBuilder?

Thanks,  
Stefan
