this is using c:/Program\ Files\ (x86)/Debugging\ Tools\ for\ Windows/dbghelp.dll for windbg 6.3 which has more dependencies and seems more difficult to support than the DDK one I used to use. xref issue #963 .

for drmem issue #1067 I was trying a dynamic drsyms as another workaround to avoid sscanf in libcmt.
I ran "-leaks_only -no_count_leaks -no_zero_stack -no_track_allocs" also doing debug DR -checklevel 1
some curiosities (xref issue #961 ):
[ RUN ] DiskCacheBackendTest.RecoverInsert [13308:9664:1030/155744:1314835550:WARNING:backend_impl.cc(1929)] Destroying invalid entry.

2 more of those
then:
