Thank you for the report. Verified as described.

You didn't mention how you built this, but let me give you some background: On most Unix systems, files with the extension '.so' are shared libraries and so for example on Linux udf_example.c gets compiled into udf_example.o and this is contained in both udf_example.a and udf_example.so. The '.a' extension tells Linux that this is a static library, so there need be a '.so' file as well, in order to load dynamically. On AIX, there doesn't have to be a '.so' file, since a '.a' file can hold dynamically loaded things as well. From version 5.0.40 on, however, the MySQL binaries are built to have '.so' libraries. Do you really mean that the udf test fails? Or do you mean this result: udf [ skipped ] Test requires: 'have_udf_example'

I really mean udf test fails.

We built mysql with -brtl in LDFLAGS. The -brtl flag enables runtime linking and causes GNU libtool to build shared libraries with the .so extension.

Noted in 5.0.44, 5.1.20 changelogs. On some systems, udf_example.c returned an incorrect result length. Also on some systems, mysql-test-run.pl could not find the shared object built from udf_example.c.
Description: The udf test fails on AIX because it can not find the library udf_example.so. It can not find the library because AIX until 5.3 does not look at LD_LIBRARY_PATH when doinf dlopen() it looks at the env var LIBPATH. How to repeat: build and run the tests on AIX < 5.3 Suggested fix: Note that I added SHLIB_PATH there also, it is the shared library path environment variable used on hp-ux.
