I encourage OpenLDAP to fix the undefined behavior. OpenLDAP is an important project, and the undefined behavior is causing too many tangential problems.

Undefined behavior is not a bug, nor is it prohibited by the C spec. It is a necessary part of the language for its intended use as a system programming language, writing machine-specific programs. Anyone who says it is prohibited by the spec is wrong.

The kernel recently got bitten using the same pattern of unaligned short pointers through casts. GCC produced code which corrupted initramfs during unpacking.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100363.

OpenLDAP should fix that code.
