I guess I should open a bug in the upstream bugzilla?
this crash happens every time mysqld is started without --skip-slave.
use flags are as follows:
[ebuild R ] dev-db/mysql-5.1.66 USE="ssl -berkdb -big-tables -cluster -community -debug -embedded -extraengine -latin1 -max-idx-128 -minimal -pbxt -perl -profiling (-selinux) -static {-test} -xtradb" 0 kB
tried debug, but got a warning about it being broken since 5.1.51
I enabled the general_log, it appears that mysqld parses the relay_logs, starts inserting data from them to the local db, but crashes after a few seconds. based on the relay_log it succeeds in inserting small amounts of data each time it is started. the last sequences are
2 Query BEGIN
2 Query COMMIT /* implicit, from Xid_log_event */
2 Query BEGIN
2 Query COMMIT /* implicit, from Xid_log_event */
the last meaningful sql command is a simple insert.
I compiled the package with -ggdb and this would be the trace:
