When failing in build_address_map, we free the unit that's currently being handled in the loop, but the ones that already have been allocated are leaked. Fix this by keeping track of allocated units in a vector, and releasing them upon failure. Also, now that we have a vector of allocated units, move the freeing upon failure of the abbrevs associated with each unit to build_address_map, and remove the now redundant call to free_unit_addrs_vector. Bootstrapped and reg-tested on x86_64. 2018-12-28 Ian Lance Taylor <iant@golang.org> Tom de Vries <tdevries@suse.de> PR libbacktrace/88063 * dwarf.c (free_unit_addrs_vector): Remove.
