From: Niksa Jurinovic <nik...@jurinovic.de> To: bu...@lists.mysql.com Subject: Bug in embedded libmysqld library or configuration problem

mysql-4.0.1-alpha, Linux Mandrake 8.1, Kernel 2.4.8

I have configured and compiled source code as always, without any problems. 'make test' was successful with all 144 tests passed. The classic combination client/server works fine. Unfortunately, when I try to start the standalone program 'mysql' (client linked with server in ../libmysqld/examples directory) I get

Segmentation fault (core dumped).

In fact, the program starts and mysql> prompt occurs. When I type 'help', help is executed. One could think that all is OK. But when I issue a query, the program aborts with 'segmentation fault'. Furthermore, it is enough to start the program and type 'quit' and 'segmentation fault' occurs.

The same is with 'test_libmysqld.c' program built with 'GNUmakefile', both extracted from 'manual.txt'. Compilation was OK, butwhen I start standalone executable program - Segmentation fault (core dumped).

I experimented adding and changing some options and variables in /etc/my.cnf file inside groups

[mysql_SERVER]/[test_libmysqld_SERVER], [server], [embedded]

but without any results. I also tried without any my.cnf file with default (compiled) variable values - and nothing!

Is it bug in embedded libmysqld library or configuration (my.cnf) problem?

Simply compile and start 'mysql' standalone program in ../libmysqld/example/ directory of original mysql-4.0.1-alpha source distibution.
