>  Then why does the following code fail?

  To find out, run /bin/perl.8.6.exe under gdb/insight and breakpoint sbrk.
You'll see that VirtualAlloc is failing.  By reassigning $eip to
GetLastError immediately after one of the failing calls, you'll see that the
problem is error code 487 - ERROR_INVALID_ADDRESS.  Perhaps there's
something else occupying the memory map that prevents the heap from being
extended contiguously.

  In any case, you should be able to improve things by setting the
heap_chunk_in_mb registry key.  Turn it up waaaay big!


    cheers,
