Summary0000283: Crash in erlang grade with io.call_system_return_signal
DescriptionWhen the test program for the JSON library at <https://github.com/juliensf/mercury-json> is built in the
erlang grade and run (i.e by doing make runtests), it results in the following abort:

{"init terminating in do_boot",{{badmatch,{"-n 0","\n"}},[{mercury__io,'-call_system_return_signal_4_p_0/1-fun-0-',1,[{file,"Mercury/erls/mercury__io.erl"},{line,5792}]},{mercury__io,call_system_return_signal_4_p_0,1,[{file,"Mercury/erls/mercury__io.erl"},{line,5778}]},{mercury__io,call_system_4_p_0,1,[{file,"Mercury/erls/mercury__io.erl"},{line,5749}]},{test_json,run_test_3_p_0,1,[{file,"Mercury/erls/test_json.erl"},{line,285}]},{test_json,'-main_2_p_0/0-fun-5-',2,[{file,"Mercury/erls/test_json.erl"},{line,190}]},{mercury__list,foldl_4_p_2,5,[{file,"Mercury/erls/mercury__list.erl"},{line,5455}]},{test_json,main_2_p_0,0,[{file,"Mercury/erls/test_json.erl"},{line,195}]},{test_json,mercury__main_wrapper,0,[{file,"Mercury/erls/test_json.erl"},{line,58}]}]}}

Adjust the hacky shell code on io.m:9742. The -n in "echo -n $?" is being printed literally.

It doesn't seem trivial to make it not print it literally :-( I'll leave this until after the 13.05 release -- the
existing code is not very portable anyway.

Looks like you want to use open_port instead, e.g.

Yes, I also saw that thread.
