My application crashes. In code I can easily read stack addresses to
backtrace problem. Question is is it possible to learn which routine
contains specified address? Of course in code (not from IDE)

If you have an unstripped original with debug info (-gl), it should be
possible on cmdline GDB.

Doing it yourself pretty much amounts to writing a binary loader. Not
trivial

Yes, but I was thinking about doing this to generate more detailed
crash reports but I can't expect all users to have knowledge of gdb (I
know that I can do it with gdb)

You can hook the traceback generation. Essentially you just copy unit
lineinfo, and make it output to a file, the eventlogging service or
whatever instead of stdio.

See the src of lineinfo to see how it works
