You should test build with bundled zlib.
It should not be bug of MySQL, but your /lib/libz.so.1.2.3.4.

The bundled zlib seems not to have such function "inflateReset2".

mysql-5.1.56_test/zlib> grep inflateReset2 *
mysql-5.1.56_test/zlib>

[Stewart Smith (stewart)]

This is probably one of those zlib warnings that are false positives (see zlib FAQ) and i think we may have another bug open for this (we should add suppressions *OR* switch to always using bundled zlib)

[Laurynas Biveinis (laurynas-biveinis)]

This was a legitimate warning, see http://bugs.mysql.com/bug.php?id=59874 and http://lists.mysql.com/commits/133000.

[Laurynas Biveinis (laurynas-biveinis)]

This is not an upstream bug http://bugs.mysql.com/bug.php?id=59874. Its stacktrace is in zlib deflate, and the stacktrace of this one is in zlib inflateInit. These two issues are only related in that both originate in zlib, otherwise they are not.
