Some Sanity check fails about gpuowl HOT 6 CLOSED

Hi Mihai, I have rerun cppcheck locally, there is still 1 warning and 1 error, let alone the style issue:

gpuowl_5.0/gpuowl$ cppcheck --enable=all --quiet .
[GCD.h:11]: (style) The class 'GCD' does not have a constructor.
[./Result.cpp:24]: (information) Skipping configuration 'REV' since the value of 'REV' is unknown. Use -D if you want to check it. You can use -U to skip it explicitly.
[common.cpp:16]: (warning) Return value of function fopen() is not used.
[common.cpp:16]: (error) Return value of allocation function 'fopen' is not stored.
[./gpuowl.cpp:13]: (information) Skipping configuration 'REV' since the value of 'REV' is unknown. Use -D if you want to check it. You can use -U to skip it explicitly.
(information) Cppcheck cannot find all the include files (use --check-config for details)

I don't get the warning+error when I run cppcheck with the same arguments on my system. I also looked at the source at that location (common.cpp:16), and it seems to me that cppcheck is wrong (it's a red herring).

Then probably it is a Debian specific issue or then it is a cppcheck issue.
Maybe it is the case to file a cppcheck bug.
I am going to use the current source as it is for packaging.

Hi Mihai, my system is: #1 SMP Debian 4.9.130-2 (2018-10-27)

this is the output of uname -v command, can you post yours?

from gpuowl.

~$ uname -va
Linux x2 4.18.0-12-generic #13-Ubuntu SMP Wed Nov 14 15:17:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

from gpuowl.

I am running version 1.76.1 of cppcheck, it is probably earlier than your version.
