This is mainly a question if I should fill a bug or not :-)

On a box with: gcc (GCC) 4.1.0-beta20060210 (prerelease) glibc-2.3.6-r2

I've tryed to compile mysql 5.1.6, using the following configure options:

./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --program-suffix=-501 --libexecdir=/usr/sbin --sysconfdir=/etc/mysql-501 --localstatedir=/var/lib/mysql-501 --sharedstatedir=/usr/share/mysql-501 --libdir=/usr/lib/mysql-501 --includedir=/usr/include/mysql-501 --with-low-memory --enable-assembler --enable-local-infile --with-mysqld-user=mysql --with-client-ldflags=-lstdc++ --enable-thread-safe-client --with-comment="Gentoo Linux mysql-5.1.6_alpha-r30" --with-unix-socket-path=/var/run/mysqld/mysqld.sock --with-zlib-dir=/usr --with-lib-ccflags=-fPIC --without-readline --without-docs --enable-shared --enable-static --without-libwrap --with-openssl --with-debug=full --with-bench --with-server --with-embedded-server --with-extra-tools --with-innodb --without-raid --with-innodb --with-extra-charsets=all --without-berkeley-db --with-geometry --without-ndbcluster --without-big-tables --with-ndb-binlog --without-embedded-privilege-control --without-embedded-server --with-archive-storage-engine --with-csv-storage-engine --with-blackhole-storage-engine --with-federated-storage-engine --with-partition --with-max-indexes=128 --with-row-based-replication --build=i686-pc-linux-gnu

without too much luck, the server crash easy and in a reproducible manner, first to make it start the "mysql.time_zone_leap_second" table needed to be removed. then the server could start with the following options:

mysqld-501 --no-defaults \ --skip-innodb --skip-name-resolve --skip-networking \ --server-id=51 \ --skip-grant-tables \ --log=/tmp/mysqld.sql \ --debug=d:t:i:o,/tmp/mysqld.trace \ --one-thread \ --user=mysql \ --datadir=/srv/mysql-501/ \ --socket=/var/run/mysqld/mysqld-501.sock \ --pid-file=/var/run/mysqld/mysqld-501.pid \

then it's possible to connect to the server using the "mysql" program, but "use" whatever database crash the server, the only way to make it work is to add the "-A" option to the command, avoiding to perform the table/fields scan.

I've tried to strip down the trace at this one:

>bitmap_init T@-1212987: | | | | | | | | | | <bitmap_init ^^^^^^^ it stop here

but it does not show anything strange to me, the error message shown is :

mysqld-501: pthread_mutex_lock.c:108: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed. mysqld got signal 6; [...]

nothing very useful follow, I forgot the omit-frame-pointer in CFLAGS .

A so easyly crashing server make me think that either the used options are totally unsupported, or if there was a bug it has already fixed, from this the question, "do you want a bug report?" maybe with a better stack trace and some more debug ?
