Ivan Prisyazhnyy	0836efd830	tracing: test/boost/tracing: fix use after free ... fixes AddressSanitizer: stack-buffer-underflow on address 0x7ffd9a375820 at pc 0x555ac9721b4e bp 0x7ffd9a374e70 sp 0x7ffd9a374620 Backend registry holds a unique pointer to the backend implementation that must outlive the whole tracing lifetime until the shutdown call. So it must be catched/moved before the program exits its scope by passing out the lambda chain. Regarding deletion of the default destructor: moving object requires a move constructor (for do_with) that is not implicitly provided if there is a user-defined object destructor defined even tho its impl is default.

Avi Kivity	6641353854	tracing: remove static class_registry ... Static class_registries hinder librarification by requiring linking with all object files (instead of a library from which objects are linked on demand) and reduce readability by hiding dependencies and by their horrible syntax. Hide them behind a non-static, non-template tracing backend registry. Message-Id: <20181229121000.7885-1-avi@scylladb.com>	2018-12-31 13:24:54 +00:00
