<div dir="ltr" >This was working on a debug tool for the IBM JVM. When we added the <strong>MiniDumpWithFullMemoryInfo</strong> to our calls to <strong>MiniDumpWriteDump</strong> we found it inserted blank ranges to keep the regions in the <strong>MINIDUMP_MEMORY_INFO_LIST</strong> structure contiguous. I checked a dump just now and it has a 8 Tb region without and access flags inserted in the middle, probably because of a gap in the addresses the libraries were loaded at, but it hasn't added an enormous one at the end.</div>

<div dir="ltr" >I guess I was trying to ask whether the LLDB API would report a region like that or not really but if we use the SBMemoryRegionInfo iteration model it won't really matter - there would be an equivalent blank one there anyway so it doesn't make any difference.</div>

<div> </div>
<div>Are you saying that's a bug in the minidump itself or in LLDB's handling of it? If the latter, please send me the details (e.g., which flags trigger this behavior), and I'll see what I can do about it.</div>
