--- Comment #11 from Ian Lance Taylor <ian at airs dot com> --- libbacktrace is all about stack backtraces. It is not about handling exceptions. libbacktrace handles inlined calls and hand written trampolines, assuming the DWARF information is correct. libbacktrace does not currently handle sibling calls; it could, based on http://www.dwarfstd.org/ShowIssue.php?issue=100909.2, but nobody has implemented it. The glibc backtrace_symbols call is a simpler function that is not nearly as powerful as libbacktrace.
