Add test-cases b2test_buildid and b3test_dwz_buildid. The last one triggers the segfault fixed by "[backtrace] Avoid segfault" ( r268275 ). 2019-01-29 Tom de Vries <tdevries@suse.de> * install-debuginfo-for-buildid.sh.in: New script. * Makefile.am (check_PROGRAMS): Add b2test and b3test. (TESTS): Add b2test_buildid and b3test_dwz_buildid. * Makefile.in: Regenerate. * configure.ac (HAVE_ELF): Set with AM_CONDITIONAL. (READELF): Set with AC_CHECK_PROG. (install-debuginfo-for-buildid.sh): Generate with AC_CONFIG_FILES. * configure: Regenerate. * elf.c (SYSTEM_BUILD_ID_DIR): Factor out of ... (elf_open_debugfile_by_buildid): ... here.

The libbacktrace library Initially written by Ian Lance Taylor <iant@google.com> The libbacktrace library may be linked into a program or library and used to produce symbolic backtraces. Sample uses would be to print a detailed backtrace when an error occurs or to gather detailed profiling information. The libbacktrace library is provided under a BSD license. See the source files for the exact license text. The public functions are declared and documented in the header file backtrace.h, which should be #include'd by a user of the library. Building libbacktrace will generate a file backtrace-supported.h, which a user of the library may use to determine whether backtraces will work. See the source file backtrace-supported.h.in for the macros that it defines. As of September 2012, libbacktrace only supports ELF executables with DWARF debugging information. The library is written to make it straightforward to add support for other object file and debugging formats.
