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. (build_address_map): Keep track of allocated units in vector. Free allocated units and corresponding abbrevs upon failure. Remove now redundant call to free_unit_addrs_vector. Free addrs vector upon failure. Free allocated unit vector. Co-Authored-By: Tom de Vries <tdevries@suse.de> From-SVN: r267443 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
