Gdb prints as many stack levels it can.

Something prevents it from going further. 
There could be several causes:
- stack corrupted (by your program)
- signals (on some platforms gdb can't properly unwind past sighandler)
- stack-switching libraries.

I often look at 200 stack calls (and sometimes at 20000, when my
recursion goes infinite :(.

Nothing special needs to be done to get this many levels from gdb.
