All, The attached patch adds a NULL entry at the end of the array of options accepted by 'set arm fallback-mode' and 'set arm force-mode'. Thus ensuring GDB doesn't go wandering off trying to print garbage from beyond the end of an array. Can someone please review and approve? Thanks, Matt gdb/ChangeLog: 2010-10-11 Matthew Gretton-Dann * arm-tdep.c (arm_mode_strings): Add NULL entry at end of array. -- Matthew Gretton-Dann Principal Engineer - PDSW Tools ARM Ltd
