(Get the code!)
tcsh fails to parse null command substitution:
% echo ````
Segmentation fault (core dumped)
%
% echo ````
Segmentation fault (core dumped)
Segmentation fault (core dumped)
%
etc.
Additionally, the shell's own error message is itself written onto standard output, instead of standard error.
This is a regression. In tcsh-6.10 and earlier versions, the parser handles null command substitution correctly:
% echo ``
%
This bug has been confirmed to exist in tcsh-6.17.02 in Oneiric. No further details are currently available.
