Regression in libthr on ia64

[Marcel Moolenaar]

Gang,

I have a small threaded program that I normally use for basic testing.
Nothing fancy. The source can be found here:
	http://www.xcllnt.net/~marcel/t.c

This simple program does not work anymore with libthr. This is what I
get:
itanium% ./thr
cpu0: boot

and that's as far as it goes. ps(1) shows:

 4293  d0  SL+    0:00.01 ./thr
 4293  d0  SL+    0:00.01 ./thr
 4293  d0  SL+    0:00.01 ./thr
 4293  d0  SL+    0:00.01 ./thr
 4293  d0  SL+    0:00.01 ./thr
 4293  d0  SL+    0:00.01 ./thr

and top gives me:

 4293 marcel    20    0  5048K  1856K pause    0:00  0.78%  0.78% thr
 4293 marcel    20    0  5048K  1856K pause    0:00  0.00%  0.00% thr
 4293 marcel    20    0  5048K  1856K pause    0:00  0.00%  0.00% thr
 4293 marcel    20    0  5048K  1856K pause    0:00  0.00%  0.00% thr
 4293 marcel    20    0  5048K  1856K pause    0:00  0.00%  0.00% thr
 4293 marcel    20    0  5048K  1856K pause    0:00  0.00%  0.00% thr
                                                                                
I can kill the program with ^C.

If I link staticly, I have more action:

itanium% ./thr
cpu2: boot
cpu3: boot
cpu3: data at 0x600000000001a080
cpu3: data at 0x600000000001a080
cpu_dtor: ptr=0x600000000001a080
cpu0: boot
cpu0: data at 0x600000000001a080
cpu0: data at 0x600000000001a080
cpu_dtor: ptr=0x600000000001a080
cpu1: boot
cpu2: data at 0x600000000001a080
cpu2: data at 0x600000000001a080
cpu_dtor: ptr=0x600000000001a080
                                                                                
But still it hangs. ps(1) and top(1) show:
 4827  d0  SL+    0:00.01 ./thr
 4827  d0  SL+    0:00.01 ./thr
 4827  d0  SL+    0:00.01 ./thr

 4827 marcel    20    0  2864K   504K pause    0:00  0.00%  0.00% thr
 4827 marcel    20    0  2864K   504K pause    0:00  0.00%  0.00% thr
 4827 marcel    20    0  2864K   504K pause    0:00  0.00%  0.00% thr

It doesn't matter if I compile with -DWITH_SLEEP or not.

Is this a known issue? Is there some work in progress still?
