Bug #4117

Updated by Michael Kay almost 6 years ago

**SUMMARY** 

 This problem was caused by attempting to inline a function call to a function in a different package, where the called function accessed global variables private to that package. 

 **ORIGINAL REPORT** 


 We are using Saxon 9.9 EE/N.  
 Following code throws exception java.lang.AssertionError
