There is a bug (bin/41671) in FreeBSD's gcc that causes it to emit bad
debug information when using the stabs format (which is the default).
In earlier versions of GDB the effects were rather limited, but
starting with GDB 5.3 the influence is much more prominent.
As a result GDB tends to place breakpoints on functions before the
function prologue, and information about function parameters and local
variables is lost. In earlier versions of GDB the effects were rather
limited, but starting with GDB 5.3 the influence is much more
prominent. As a workaround, compile your code with -gdwarf-2.
