When use/import does not specify module name, parser fails to produce an error message
Consider the following sac program:
use /* missing */ : {test};
As it can be seen, we accidentally missed the name of the module we are using. The compiler dies, which is correct; but no error message is emitted:
$ sac2c_p y.sac
abort: Failed to construct a syntax tree for `y.sac'
compilation failed while Loading SAC program.
The sac2c version is:
sac2c 1.2-beta-BlackForest-611-g777dc
