From: Niksa Jurinovic To: bu...@mysql.com Subject: Segmentation fault starting mysql client linked with embedded library

Mysql client in classic client-server combination works fine. Only mysql client linked with embedded libmysqld.a library crashes with segmentation fault at start time.

Start mysql client linked with embedded library in ../libmysqld/examples directory.

The problem didn't exist in mysql-4.0.12. It seems the problem is in mysql.cc source code with points related to embedded library. Linked with libmysqlclient, it works fine. At the other side, any other program linked with embedded libmysqld.a library also works fine. Only combination mysql.cc - libmysqld.a produces segmentation fault.
