Extended Description

Please merge 221c5af into the 10.x branch. This fixes a new -Werror warning from clang 10.0.0 in libunwind:

In file included from libunwind/src/libunwind.cpp:22:
libunwind/src/UnwindCursor.hpp:1455:51: error: operator '?:' has lower precedence than '|'; '|' will be evaluated first [-Werror,-Wbitwise-conditional-parentheses]
_info.flags = isSingleWordEHT ? 1 : 0 | scope32 ? 0x2 : 0; // Use enum?
~~~~~~~~~~~ ^
libunwind/src/UnwindCursor.hpp:1455:51: note: place parentheses around the '|' expression to silence this warning
_info.flags = isSingleWordEHT ? 1 : 0 | scope32 ? 0x2 : 0; // Use enum?
^
