Don't think breaking on such a call should work, anyway.  How would gdb 
know which (of possibly many strcpy calls) to break on.  All?  Then what 
- gdb stepping through it would be useless (no debug info).  Just break 
on char_array2.c:6 .  Want to trace all calls to strcpy?  Add your own 
and break on its first line (compiler will howl but do what you said).  
And by the way, if you do, with "break strcpy", my gdb will in fact 
break on the FIRST call only !
