The following model throws a segmentation fault:

model dd
  parameter Integer N = 1;
  Integer nremTAout;
  Integer[N] remTAout;
algorithm
  for i in 1:N loop
    nremTAout := 1 + nremTAout;
    remTAout[nremTAout] := i;
  end for;
end dd;

[Martin Sjölund]

Shouldn't it throw a segmentation fault though? It never resets remTAout to 0.

[Lennart Ochel]

I guess you mean nremTAout:
It should be set to zero due to the specification [section 11.1.2]:

An algorithm section is conceptually a code fragment that remains together and the statements of an algorithm section are executed in the order of appearance. Whenever an algorithm section is invoked, all variables appearing on the left hand side of the assignment operator ":=" are initialized (at least conceptually):

• A non-discrete variable is initialized with its start value (i.e. the value of the start-attribute).
• A discrete variable v is initialized with pre(v).

[Martin Sjölund]

All integers are discrete.

[Lennart Ochel]

Well, that is of course true ...

[Lennart Ochel]

The following model throws a segmentation fault:

model dd
  parameter Integer N = 1;
  Integer nremTAout;
  Integer[N] remTAout;
algorithm
  nremTAout := 0;
  for i in 1:N loop
    nremTAout := 1 + nremTAout;
    remTAout[nremTAout] := i;
  end for;
end dd;

Postponed until 1.9.1

[Martin Sjölund]

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

[Martin Sjölund]

Milestone changed to 1.9.3 since 1.9.2 was released.

[Martin Sjölund]

Moved to new milestone 1.9.4

[Martin Sjölund]

Milestone pushed to 1.9.5

[Martin Sjölund]

Milestone renamed

[Martin Sjölund]

Ticket retargeted after milestone closed

[Martin Sjölund]

Milestone moved to 1.12.0 due to 1.11.0 already being released.

[Francesco Casella]

As of v1.13.0-dev-188-g2c5818d the model in comment:6 works correctly
