Re: [clang] Crash "ha_xtradb.so" (Undefined symbol "_increment_page_get_statistics")
Unfortunately we do not support the clang compiler at the moment.

However, we would be happy to accept patches to make clang work, and also happy to try to answer concrete questions to help.

Re: [clang] Crash "ha_xtradb.so" (Undefined symbol "_increment_page_get_statistics")
just checked, clang/freebsd appears to work in 5.5. I realize that the bug is for 5.2, but here fix is not likely, it might be better to use gcc/g++, or to link xtradb into the server rather than having it as plugin (all MariaDB own distributions do that)
