Sometimes the program counter points to a non-readable memory address after a crash. When we run the
gdb_cmds.txt
file in funfuzz, commands likex/8i $pc
will fail. I'm not sure if this is the right solution, but I just check for the text 'Error in sourced command file' in thecrashInstruction
variable and set the instruction toNone
so it's ignored. I tested this locally and it seems to work.Fixes #496.
