<pre>Porting this from a Firefox bug report at
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1458109">https://bugzilla.mozilla.org/show_bug.cgi?id=1458109</a>
Using this build:
<a href="https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.zip">https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.zip</a>
whose PDBs are here:
<a href="https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.crashreporter-symbols-full.zip">https://queue.taskcluster.net/v1/task/GoXhaNayTkig6I6H9szsYw/runs/0/artifacts/public/build/target.crashreporter-symbols-full.zip</a>
MSVC's debugger can't invoke functions in xul.dll. Member functions give a
message like: 'Function nsIFrame::DumpFrameTree has no address, possibly due to
compiler optimizations.'
Non-member functions give a message like 'identifier "DumpJSStack" is
undefined'.
This happens when the binary is linked with lld-link, regardless of whether the
compiler was cl or clang-cl. WinDbg can see these symbols with 'x' just fine,
regardless of linker.</pre>
