Record with vectors, zeros(), size()

[c.schulze@…]

model emptyVector2
  record R
    parameter Real x[:]=zeros(size(x,1));
  end R;
  R r;
end emptyVector2;

here omc.exe freezes. (r15030)

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]

The milestone of this ticket has been reassigned to "Future".

If you think the issue is still valid and relevant for you, please select milestone 1.13.0 for back-end, code generation and run-time issues, or 2.0.0 for front-end issues.

If you are aware that the problem is no longer present, please select the milestone corresponding to the version of OMC you used to check that, and set the status to "worksforme".

In both cases, a short informative comment would be welcome.

With omc -d=newInst emptyVector2.mo we get a stack overflow and omc crashes.
I don't quite get what would be the result of this except error if you don't give r.x when you declare r.

[c.schulze@…]

This report is just about the crash.

The Dymola error message is:
Failed to expand the variable r.x
and its definition equation:
zeros(size(r.x, 1))

[Francesco Casella]

Still valid in 1.16.0-dev-170-g3af6123f8
