Partially fixed. Patch is for current OPENLDAP_REL_ENG_2_4, but applicable for master.

Thanks, the patch makes sense. But if only partial, what else is still crashing?

Stable crash in a 5 seconds after the 4x-cluster resumes from split-brain condition:

Program terminated with signal SIGSEGV, Segmentation fault. #0 __memcpy_sse2_unaligned () at ../sysdeps/x86_64/multiarch/memcpy-sse2-unaligned.S:116 116 ../sysdeps/x86_64/multiarch/memcpy-sse2-unaligned.S: Нет такого файла или каталога.

Seems to be fixed completely. The last SIGSEGV is inducted by a "dreamcatcher" feature (ITS#7974). I already fixed the "dreamcatcher", currently we are re-testing it.
