>Description:
      For some reason the read of the trailing dump header fails with
errno=14 (Bad Address) when the 1M buffer is allocated on the stack.
Smaller size buffers up to roughly 128K works.

Current work-around: allocate the 1M buffer on the heap.

State-Changed-When: Wed Oct 8 00:37:34 PDT 2003 
State-Changed-Why:  
No change. The problem is attributed to a compiler bug. The current 
state of affairs is that the problem is not reproducable after 2 
compiler upgrades.
