Applying templates directly to a result of document() function can be 
dangerous sometime due to the fact that the result is always root node 
and template for "/" is in use. Without a mode it could cause infinite 
looping, in your case you probably don't have template for root node in 
info_mode mode and built-in template as usual loses your parameter.
Try to add some location path after document() function to eliminate 
built-in templates processing as they don't pass parameters.

<xsl:apply-templates
     select="document(concat($filename_base, '.xml'))/*"
     mode="info_mode">

But anyway it's perfectly legal xslt stylesheet and xalan shouldn't die 
on it, probably you have found a bug.
