I only get that when compiling with debug=yes.
gcc version 4.9.2 (Ubuntu 4.9.2-0ubuntu1~14.04)
from stockfish.
gcc is known to suffer from false positives in this area... especially with -O3

Thanks for the link. Sadly it seems they simply don't care (after a failed
first attempt) to fix it.

Ignore for SF6.
syzygy implementation will be worked on during SF7 anyway.

Good news. They have fixed the bug in the gcc5 branch :)

Hi all,
This just for the record, I have recently installed the latest MinGW and, as reported by Felix on FishCooking also, it seems the issue is not fixed/back again, at least with current Stockfish master, you get the same warning. My version of GCC:
C:>GCC --version
GCC (i686-posix-dwarf-rev0, Built by MinGW-W64 project) 5.3.0
Copyright (C) 2015 Free Software Foundation, Inc.

Still unfixed gcc bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59124
from stockfish.
this issue can now be closed.
What about making gcc's -Werror (all warnings are error) part of the makefile now ?
from stockfish.
With Marco's syzygy rewrite and gcc-6.1.0 I no longer get this warning
from stockfish.
Fixed by c0bb0415394179e9c771
from stockfish.
I get these warnings under MSVC w/ the new C++ syzygy implementation.
tbprobe.cpp(536): warning C4267: 'initializing': conversion from 'size_t' to 'uint32_t', possible loss of data
tbprobe.cpp(547): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data
tbprobe.cpp(582): warning C4244: '=': conversion from 'uint64_t' to '`anonymous-namespace'::Sym', possible loss of data
tbprobe.cpp(983): warning C4267: '=': conversion from 'size_t' to 'int', possible loss of data
tbprobe.cpp(1010): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data
from stockfish.
Thanks for reporting. I knew them also by looking at Travis ci output after
each commit.
I don't plan to fix them because they are wrong (gcc and clang don't report
them) and the fix if is a bunch of casts it is very ugly too.
If you are able to fix them without using casts then it's ok.

You are receiving this because you modified the open/close state.
