Thanks for the pointer. I have managed to extract the source and to
compile the backtrace code by using dladdr() instead of _dl_addr().
However, all I see in the backtrace is addresses which do not get
resolved into symbolic names.
Further testing shows that dladdr() succeeds, but returns an empty
file name and the "nearest" symbol name `_start'. Do I have to use
special compile-time or link-time options? At the moment, I use -g
-fno-omit-frame-pointer.
