python-gdb now catchs UnicodeDecodeError exceptions when calling
string().
(cherry picked from commit d22fc0b)
When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.
