mysqld crashes on shutdown after running TokuDB tests on Ubuntu



    • 10.1.9-3


      Login to a Ubuntu-15.10 x86_64 machine, e.g. like this:

      bar@ubuntu15:~$ uname -a
      Linux ubuntu15 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
      bar@ubuntu15:~$ cat /etc/debian_version 

      Run the following commands:

      git clone -b 10.0 git@github.com:MariaDB/server.git
      mkdir builddir
      cd builddir/
      export CFLAGS="-g -Wl,-Bsymbolic-functions "
      export CXXFLAGS="-g -Wl,-Bsymbolic-functions "
      cmake -DCMAKE_INSTALL_PREFIX=/usr \
          -DWITH_SSL=bundled \
          -DWITH_ZLIB=system \
          -DBUILD_CONFIG=mysql_release \
      make -j6
      cd mysql-test
       ./mtr  tokudb_bugs.db823

      It generates the following output:

      TEST                                      RESULT   TIME (ms) or COMMENT
      worker[1] Using MTR_BUILD_THREAD 300, with reserved ports 16000..16019

      ***Warnings generated in error logs during shutdown after running tests: tokudb_bugs.db823
      151106 13:24:13 [ERROR] mysqld got signal 11 ;
      Attempting backtrace. You can use the following information to find out
      Only  1  of 2 completed.
      The servers were restarted 0 times
      Spent 0.158 of 6 seconds executing testcases
      Warnings in log: All 1 tests were successful.
      Errors/warnings were found in logfiles during server shutdown after running the
      following sequence(s) of tests:
      mysql-test-run: *** ERROR: There where errors/warnings in server logs after running test cases.

      Now If I run with gdb:

       ./mtr  --gdb tokudb_bugs.db823

      it displays the following stack trace:

      Program received signal SIGSEGV, Segmentation fault.
