This model should not simulate

[Francesco Casella]

Try simulating this model with the latest nightly build of OMEdit

model M
  parameter Real p;
equation 
 p =10;
end M;

The following errors are reported:

[1] 19:16:34 Symbolic Error
Too many equations, over-determined system. The model has 1 equation(s) and 0 variable(s).

[2] 19:16:34 Translation Error
[M: 4:2-4:7]: Internal error p = 10.0 has size size 1 but 0 variables ()

[3] 19:16:34 Translation Warning
[M: 2:3-2:19]: Parameter p has no value, and is fixed during initialization (fixed=true), using available start value (start=0.0) as default value.

but then C code is generated and a simulation is run(!), with result p = 0.

This makes no sense, the compilation should be aborted after reporting error number 1.

That is because translateModel returns true and just reports the error messages. It should return false in this case.
