Description:
I compiled a 32bit Linux binary using the 5.1.35-snapshot20090630 sources taken from
pushbuild (based on the mysql-5.1-wl1326 source tree). Running the entire GIS tests
results in a segfault when running the main.subselect_gis test - see the attached log
file for a backtrace (BugDB would not let me post it in the description).
Interestingly, this only happens if there are other tests run before the failing test.
Running subselect_gis alone passes, and I did not observe this failure in pushbuild as
well:

How to repeat:
Take the mysql-5.1.35-snapshot20090630.tar.gz source tarball (from pushbuild) and compile
it using the following options:
CFLAGS='-g -O2 -Wall -DUNIV_LINUX' CXX='g++' CXXFLAGS='-g -O2 -Wall -Wall
-fno-implicit-templates -fno-exceptions -fno-rtti' LDFLAGS='-g -rdynamic ' ASFLAGS='-g'
./configure --enable-thread-safe-client --enable-local-infile --with-pic
--with-client-ldflags=-static --with-mysqld-ldflags=-static --with-zlib-dir=bundled
--without-ndb-debug --with-big-tables --with-ssl --with-readline --with-embedded-server
--with-archive-storage-engine --with-blackhole-storage-engine --with-csv-storage-engine
--with-example-storage-engine --with-federated-storage-engine --with-partition
--with-extra-charsets=all --with-innodb
Now run the subselect_gis test after another test:
$ cd mysql-test
$ ./mysql-test-run gis.test subselect_gis.test
Observe the crash documented above.
Suggested fix:
No idea how to fix this - let me know if you need any additional information or a
precompiled binary. I used gcc 4.3.1 for this build.
