Ok, so it is for distributed program. Compile the program with -g,  
keep the original copy for yourself and run "strip" on the copy that  
you distribute to your users. When you get a backtrace from a user,  
like this:

Runtime error 216 at $0000271C
   $0000271C
   $00002744
   $00024720
   $000026D0
   $000023E0
   $00001000

then you can look up the addresses in gdb:

gdb my-program-compiled-with-g-and-not-stripped
(gdb) info line *0x0000271C
Line 6 of "tt.pp" starts at address 0x2714 <TEST+20> and ends at  
0x2720 <TEST+32>.
