Elaboration in Detached Process

Elaboration in Detached Process

[Frank Mattison]

Has anyone experienced this problem, when running Ada 83 (OpenVMS)
detached?

In the following example Data_Ptr initializes correctly when running
as an interactive process.  But when running as a detached process,
this initialization raises an exception when the procedure is called:

procedure XYZ(Data_Format : in Data_Formats) is
   Data_Ptr : Data_Ptrs := new Data_Types(Data_Format);
begin
      ...

There are other cases where the elaboration seems to fail when the
process is switched to detached.  Does anyone have a suggestion as to
how to handle this?

Thanks,

Frank Mattison

Is the detached process running under DCL or without it ?

Is this Alpha or VAX ?

What version of VMS ?

What version of VAX/DEC/Compaq Ada ?

I don't have any experience, but perhaps the default stack and heap
sizes are smaller for detached processes, so you are getting
Storage_Error?
