I can't repro this in my environment via:
./configure --enable-coredump --enable-cxx-exceptions
--enable-debug-frame --enable-block-signals --enable-minidebuginfo
--enable-ptrace --enable-setjmp
make check
Guessing that it's caused by gcc-4.9.x. Perhaps try tweaking
include/compiler.h (eg: undefine PROTECTED) to find a workaround for
now?
I'm hoping that someone more familiar with the compiler issues can
propose a better solution.
