Please check if this fix is applied to your version:
https://sourceware.org/git/?p=lvm2.git;a=commit;h=c459f23565e86eb9a8a116995cda7dcaed858b9f

AFAICT all the problems you sent are the fault of the memory debugging
code, not the original problem.  You need to compile lvmetad with
debugging, but not memory debugging.  Then gdb should give relevant
backtraces.
