Today I started a new project with 4.10.0 RC (Win 7 64 bit, IIS7.5, ASP.NET 4.0) and I have come across a strange issue. When I make a call to umbraco.library.RenderTemplate from within a user control, master page or xsl, UMBRACO seems to go into a recursive loop and crashed the w3wp.exe. I setup VS2012 and ran a debug session on the usercontrol with this code in and when I passed a valid nodeID in, the user control was being called repeatedly until the call stack must have filled up and w3wp.exe crashed out.

If I pass an invalid nodeID then the page completes successfully and obviously nothing is rendered.

Can anyone else replicate this?

The xslt simply has:

<xsl:value-of select="umbraco.library:RenderTemplate(2099)" disable-output-escaping="yes"/>

And the masterpage has

  <%=umbraco.library.RenderTemplate(2099) %>

The Document Type being rendered has one template defined and has some simple HTML text in it.

Has anyone else come across this? I am wondering if it is a bug introduced in the new version.
