I am unable to reproduce this, will you run

  • make clean
  • make VERBOSE=1
    and include the build output e.g.,
[ 66%] Building C object src/CMakeFiles/hindsight_cli.dir/hs_logger.c.o
cd /work/tmp/hindsight/release/src && /usr/bin/cc  -DHINDSIGHT_CLI -D_POSIX_C_SOURCE=199506L -D_XOPEN_SOURCE=600  -std=c99 -pedantic -Werror -Wno-error=deprecated -Wall -Wextra -fPIC -O2   -o CMakeFiles/hindsight_cli.dir/hs_logger.c.o   -c /work/tmp/hindsight/src/hs_logger.c

Thanks,

@trink Does this problem fixed? I build hindsight in a docker env( docker image is centos:7) .
meet this error every time .

commented

Moving the declaration/switch before the fprintf within the lock should quiet the bogus warning. A bit annoying but if it fixes the issue I will merge it. Since you can reproduce it consistently please let me know if this https://github.com/mozilla-services/hindsight/compare/dev...issue_185?expand=1 fixes the issue, thanks.

@ruiaylin I've had the same issue. It has been fixed by upgrading gcc to 7.2.1
