Hi Dave,

Sorry for delay (even with my speedy b2k, it takes some time for optimizing
this stuff :-) ).

Finaly, here we are:

a) The same bad result with -O2 and today cvs binutils :-(

b) the pre-asm around line 146240:

(iirc b .L6999 means branch _b_ack to label .L6999 
if yes here is also text around this location:

It is well a stub table pb?

If not I will procede next step tomorrow :-)

Thanks again for your attention and patience,
