[Issue 9916] slapd crashes due to unaligned access in mdb.c on Linux SPARC

--- Comment #2 from Howard Chu hyc@openldap.org ---

Adding __attribute__((packed)) to the MDB_page struct creates some memory alignment warnings, but it will make the test cases succeed:

Interesting, since the fields of the MDB_page struct are already naturally aligned. LMDB was tested thoroughly on Sparc64 / Solaris and no such compiler attributes were needed so this requirement appears to be a compiler bug.

I've submitted a request for an account on the compile farm since we long ago decommissioned our Sparc servers (and they were only running Solaris anyway, not Linux).
