This is now bug:
https://sourceforge.net/tracker/index.php?func=detail&aid=1687704&group_id=75274&atid=551529

The bug causing this internal error occurs in this test case during the 
attempt to report:

# syntax error: The optional e.enable.hard-when feature (see 
org/erights/e/elang/syntax/syntax-props-default.txt) is currently off.
#
#   when (a) -> a(b) {}
#                     ^

This bug is now fixed (but not yet committed or released), and the above is 
successfully reported.
