Sorry this is related to the client lib, I cannot move this ticket to the correct project.

Hi,
which version of C/C do you use?

Comment by FLAESCH Sebastien [ 2018-11-07 ]

Hi Georg, as indicated in the "Environment" field: gcc 6.3.0:

$ gcc --version

I didn't ask for gcc version but for version of Connector/C.

Comment by FLAESCH Sebastien [ 2018-11-07 ]

Sorry I don't know what Connector/C version this would be: I have compiled MariaDB 10.3.3 sources.
