Hello,
I have an unexpected data-tests-logcount failure. The end of
src/data-tests.log reads:
Test data-tests-logcount condition:
(wrong-type-argument integer-or-marker-p 1431655765.0)
FAILED 26/30 data-tests-logcount
passed 27/30 data-tests-max
passed 28/30 data-tests-min
passed 29/30 data-tests-varalias-watchers
passed 30/30 data-tests-variable-watchers
Ran 30 tests, 29 results as expected, 1 unexpected (2017-10-24 10:56:32+0100)
1 unexpected results:
FAILED data-tests-logcount
I'm on 3.2.0-4-686-pae #1 SMP Debian 3.2.93-1 i686 GNU/Linux.
Colin.

What are the values of (logcount 9727) and (logcount 9999) on your
platform? They should be 11 and 8, respectively.Are there more details
about this in the file test/src/data-tests.log?
How did you invoke 'configure'? What is the output of 'gcc --version',
and of 'cat /proc/cpuinfo'?
Can you run Emacs under GDB and put a breakpoint on the Flogcount
function, and execute the above two Elisp calls while single-stepping
through Flogcount, and also disassemble Flogcount? I did that on Fedora
26 x86-64 on AMD Phenom II X4 910e, configured with
'PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig:/usr/share/pkgconfig ./configure
CC="/usr/bin/gcc -m32 -march=native -fsanitize=undefined
-static-libubsan" --enable-gcc-warnings --without-imagemagick
--with-modules', and got the following. What do you get when you try the
same thing with your configuration?

I get "Value returned is $2 = 34".
I'm sort of at the extreme limit my IT understanding level, so I may
have messed up - sorry.
Best wishes,
Colin.

These are the correct values: 46 is the Emacs representation for 11, and
34 is the Emacs representation for 8. So I'm puzzled as to why the tests
failed.
What is in test/data/data-tests.log?
What is the output of the following shell command?
src/emacs -Q -batch -eval '(message "%S %S" (logcount 9727) (logcount
9999))'
It should be "11 8".

Do you mean test/src/data-tests.log?
