Segmentation fault starting mysql client linked with embedded library

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

>Description:
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.
>How-To-Repeat:
Start mysql client linked with embedded library in ../libmysqld/examples
directory.
>Fix:
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.

Re: Segmentation fault starting mysql client linked with embedded library

Examining the stack with backtrace command this is what I get:

This GDB was configured as "i586-mandrake-linux-gnu"...
Core was generated by `./mysql'.

The problem didn't exist in mysql-4.0.12.

You mean my.cnf file, not my.conf file. But it doesn't matter. With the same
my.cnf file the problem didn't exists in mysql-4.0.12.
