Yk error - double free or corruption

[Pavel-Durov]

Error I got when running Yklua tests (YK build commit 8c8468967745e343df08966f00de02dc663945d7).

$ ../src/lua -e"_U=true" all.lua

***** FILE 'db.lua'*****
testing debug library and debug information
double free or corruption (!prev)
Aborted (core dumped)

Adding print statements resolves this error.

Closing this issue. Rebuilding YK with updated submodules fixed it.
