A following patch will make gdb_test error out if bogus arguments are
passed, which exposed bugs in a few testcases:
- gdb.python/py-parameter.exp, passing a spurious "1" as extra
parameter, resulting in:
ERROR: Unexpected arguments: {set test-file-param bar.txt} {The name of the file has been changed to bar.txt} {set new file parameter} 1
- gdb.python/py-xmethods.exp, a missing test message, resulting in
the next gdb_test being interpreted as message, question and
response! With the enforcing patch, this was caught with:
ERROR: Unexpected arguments: {p g.mul<char>('a')} {From Python G<>::mul.*} gdb_test {p g_ptr->mul<char>('a')} {From Python G<>::mul.*} {after: g_ptr->mul<char>('a')}
- gdb.base/pointers.exp, missing a quote.
