Summary0000268: Typo in :- end_module declaration leads to compiler crash.
Descriptionλ junk → cat test.m
% vi: ft=mercury ts=4 sw=4 et wm=0 tw=0

Making Mercury/asm_fast.gc/x86_64-unknown-linux-gnu/Mercury/cs/test.c
Uncaught Mercury exception:
Software Error: parse_tree.equiv_type: predicate `parse_tree.equiv_type.replace_in_item_list'/13: Unexpected: module start or end
Stack dump not available in this grade.
** Error making `Mercury/asm_fast.gc/x86_64-unknown-linux-gnu/Mercury/cs/test.c'.
Steps To ReproduceAs above.
Additional InformationThis caused me a frustrating divide-and-conquer debugging session as I tried to figure out why a re-factored module was suddenly crashing the compiler. Generally a warning/error would be preferred to crashes. ;)
TagsNo tags attached.
