When building employee.fdb on sparc64, a bus error (unaligned memory access) is produced:
sh -x -c "lockfile -1 ../../gen/Release/firebird/bin/build-db.lock && ./empbuild ../../gen/examples/employee.fdb; res=\$?; rm -f ../../gen/Release/firebird/bin/build-db.lock; exit \$res"
+ lockfile -1 ../../gen/Release/firebird/bin/build-db.lock
ERROR: http://ld.so: object 'http://libeatmydata.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

+ res=44
+ rm -f ../../gen/Release/firebird/bin/build-db.lock

Makefile.examples:125: recipe for target '../../gen/examples/employee.fdb' failed
This was introduced in 218f419, as the additional descriptors are placed back-to-back without any alignment. From gdb:
Program received signal SIGBUS, Bus error.
