Hello all,

To get useful stack traces, the mysql library needs to be be compiled with debug information and must not be stripped.
As soon as you have a library that fullfills those criteria, debugging can begin. Otherwise it's just poking around in the dark.
You could use, for example, "-g3 -fvar-track-assignments" as gcc cflags.

Kind regards
