Re: Core in XMLString

[Kshitiz Saxena]

 Thanks Alberto. It did solve the issue. I did call 
XMLPlatformUtils::Initialize() before instantiating LBConfigParser 
object, but didn't realize that static initialization was causing this 
failure.

Thanks again,

XMLString::transcode works properly only after you have invoked
