Internal Error in CallTask()

[pjc30943]

Perhaps I missed this in the native mode section of the documentation.
For code being written over from a 1281ae to a 1280n dev board, tasks which are called with parameters gives the following:

"Internal error: statement.cpp(1750), Rev.1109: unexpected parameter type for CallTask ..."

Any thoughts on why this occurs?

Any thoughts on why this occurs?

Except for a few specific issues, any program that compiles for a VM mode device should compile for a native mode device. In any event, an "Internal Error" is an indication of a problem in the compiler itself, not an error in your program.

Please post some of the code related to the issue. If you can, pare the program down to a test case that contains the smallest amount of code that still exhibits the problem. That helps us zero in on the problem quickly.

Thanks.

Here's the example:

Code: Select all

Option TargetCPU 1280n

public const taskStackSize as integer = 700
public taskStack (1 to taskStackSize) as byte

sub Main()

  callTask task(false), taskStack

end sub

sub task(byval TF as boolean)

end sub

This returns the error stated above.

Thanks for the test case. We found the cause of the problem which had a very simple solution. You can download an experimental version of the compiler with that correction (along with some other organizational changes) using the link below.

Thanks Don; that seems to have resolved the issue.
