I have a task type that acts as a semaphore for a buffer list. The
entry points for the task are Start, Seize, Release, and Stop. The task
body looks something like this:
task body Semaphore
Boolean busy;
Boolean complete;
begin
accept Start
select
when not Busy =>
accept Seize do
busy = true;
or accept Release
busy = false;
or when not Busy =>
accept Stop do
complete = true;
end select;
-- CAN'T REMEMBER THE LINE OF CODE THAT GOES HERE
end Semaphore;
My code is compiled on Solaris 7 using the VADS 6.2.3c compiler and AXI
Bindings from ATC (version 3.2).
My problem is I get a SIGILL error when I try to clear the buffer.
Could this problem be caused because a task called Seize, Release, or
Stop before Start has been called? When I checked the tasks running, I
have two suspended at select and two more suspended at fast select
(sorry...I'm at home and I was writing this at work).

If VADS 6.2.3c is an Ada compiler (instead of Ada83), why not use a
protected type ? For more efficient.
