Expected behavior

Handle input error

Actual behavior

Segmentation fault

Steps to reproduce the behavior

$ r2 -
[0x00000000]> adf
Segmentation fault (core dumped)

Additional Logs, screenshots, source-code, configuration dump, ...

in libr/core/anal.c, when command "adf" has no or wrong argument,
anal_fcn_data (core, input + 1) --> RAnalFunction *fcn = r_anal_get_fcn_in (core->anal, core->offset, -1);
returns null pointer for fnc cause segmentation fault later in ensure_fcn_range (fcn);
