Hi, I've written an implementation of the backtrace family of functions described in: http://www.kernel.org/doc/man-pages/online/pages/man3/backtrace.3.html You can find it in: http://www.netbsd.org/~christos/libexecinfo.tar.gz In addition to providing support for resolving static symbols via libelf, it also allows for formatting control of the output. Should I commit it? christos
