I was observing that `p (const char *)str` also worked in my experiment, but I’m far from a C++ expert and upon double-checking this seems to have been more of an accident than intended behaviour, because there is no operator const_pointer in basic_string that I can find. Definitely use `p str.c_str()`.
That explanation doesn't work IMO, unless `str` is a std::string pointer, which is contrary to the syntax GP suggested with `str.c_str()`.
It doesn't seem possible in actual C++ that the cast from non-pointer to pointer would work at all (even if a small string happens to be inlined at offset 0.) Like GP, I looked for a conversion operator, and I don't think it's there. Maybe it is a feature of the gdb parser.
