Sorry for the delay. I've updated the README over at GitHub https://github.com/tskardal/mysigsegv/blob/master/README.md#reproduce
This time I run the code on Ubuntu 18.10 running in virtualbox. The database runs on my host OS, but my hypothesis is that any remote server will have the same result. FWIW: I'm not sure this is a Ubuntu issue, but if not I hope you can point me in the right direction :-) Copied here for convenience: Reproduce: * First install a MySQL server somewhere (I have it installed on my host OS which is macOS). * I've tested both 5.7 and 8.0 * Create a empty database and grant access to it * Edit the source code (main.cpp) so that mysql connection information is correct * Run the application * 💥 Example: Messages before (core dumped) are the result of `SHOW VARIABLES LIKE '%version%'` mkdir build cd build/ qmake ../mysigsegv.pro make ./mysigsegv "innodb_version" = "8.0.13" "protocol_version" = "10" "slave_type_conversions" = "" "tls_version" = "TLSv1,TLSv1.1,TLSv1.2" "version" = "8.0.13" "version_comment" = "Homebrew" "version_compile_machine" = "x86_64" "version_compile_os" = "osx10.14" "version_compile_zlib" = "1.2.11" Segmentation fault (core dumped) ** Changed in: mysql-5.7 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1818985 Title: segfault in libmysqlclient when reconnecting using QMYSQL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1818985/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
