Public bug reported:

i am building stock mysql-5.1.34 and xtradb-plugin-1.0.3-5  with
mysql-5.1.34 as a dynamic plugin (ha_innodb.so) . i am not using --with-
debug while configuring.

built went fine .. and i have "ignore-builtin-innodb" in .cnf file to
completely ignore builtin innodb ..

when trying to start server with having ha_innodb.so in plugin
directory, it throws coredump

and the backtrace here ..

to debug this, i built all the binaries again with --with-debug and when trying to start server, it starts very fine without any error .. very strange .. 

so i have no clue how to debug this ..

please let me know if i need to provide more information to debug this
..
