Description:
Earlier reported `bug#59179 binlog_checksum and rpl_checksum_cache time out on Linux in release builds' analysis revealed a possible wrong compilation on ia64.
that ended up in incorrect  computation of OR with three arguments.
When the expression was split apart the correct evaluation got restored.

How to repeat:
See bug#59179 analysis and the patch.

Suggested fix:
Disassemble to find out how the machine instructions make the incorrect value
which should provide a clue about the whole issue.
