--- Comment #1 from Anastasius Focht <focht at gmx.net> ---
Hello folks,
still present, tested with 64-bit Chrome 46.0.2490.80
I'm refining the summary to indicate this includes all 64-bit apps/processes
which make use of Chromium's browser engine with native API sandboxing/hooking
scheme.
At least on my system, 64-bit 'ntdll.dll.so' can't be mapped at desired fixed
<2GB address range since 'wine64' overlaps a bit into that area:

kernel32: 0x7b800000..0x7bf02000 (ok)
ntdll: 0x7bc00000..0x7bf84000 (ought to be, can't be mapped here)
wine64: 0x7be00000..0x7c103000 (has overlap into ntdll range, causing ntdll to
be mapped in high 64-bit range)
If you move wine[64] load address a bit to higher range (don't forget to
'autoreconf -i' after modifying 'configure.ac') then 'ntdll.dll' can be
properly mapped at desired fixed base address and 'ReadProcessMemory()' on
remote process works as expected.
