Model with array of unknown size fails without error message

[perost]

The following model should output an error message, not fail silently:

model M
  Real r[:];
end M;

[sjoelund.se]

Fixed in trunk

[sjoelund.se]

Reopening as the fix added unintended error messages that were missed (ran testsuite in wrong directory)

[perost]

This doesn't actually fail anymore. It creates an array of size 1, which is worse than failing since it succeeds but does the wrong thing.

OMC 1.13.0, with the new front end, produces the following error:

[1] 23:41:08 Translation Error
[M: 2:3-2:12]: Failed to deduce dimension 1 of r due to missing binding equation.

while the old front end gives:

[1] 23:42:10 Symbolic Error
Too few equations, under-determined system. The model has 0 equation(s) and 1 variable(s).

[2] 23:42:10 Symbolic Warning
[M: 2:3-2:12]: Variable r[1] does not have any remaining equation to be solved in.
  The original equations were:

I'd say this behaviour is ok (particularly the new front end's)
