* Crashs on systems with Cyrix or other old i486 CPUs ===================================================== As reported http://bugs.mysql.com/bug.php?id=21765 MySQL will segfault on very old CPUs that do not have support for the "cpuid" instruction. * Self-build binaries that are linked against libmysqlclient15 MUST be rebuild! =============================================================================== This only affects binaries that are build on a Debian unstable/testing system before 2006-03-31 or version 5.0.19. "objdump -T myprogram | grep MYSQL_5.0" will give a couple of lines output in such a case. Until now libmysqlclient.so.15 had versioned symbols provided by a Debian patch. Now MySQL finally decided to adopt this patch but sadly chosed a different symbol name. Binaries linked against the old version of the library with my symbol name will not run with the new version with MySQL's symbol name ("version `MYSQL_5.0' not found"). The actual name /usr/lib/libmysqlclient.so.15 must stay because else binaries coming from systems other than Debian would never run on a Debian server. So the Debian package had to be renamed from "libmysqlclient15" to "libmysqlclient15off" and do now conflict with their former version. -- 2006-03-14, Christian Hammers
