Bug ID: 78710 Summary: suggest better exception text for stoi, stol, ... Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: nico at josuttis dot de Target Milestone: --- stoi("hello") currently throws an exception where what() only outputs "stoi" (nothing else). The reason is (if I analyzed it correctly): - stoi etc. pass their name (just "stoi") to __stoa as __name - __stoa calls: std::__throw_invalid_argument(__name); - which usually seems to call _GLIBCXX_THROW_OR_ABORT Some component (either __stoa() or __throw_invalid_argument()) should extend the message at least a bit. E.g. __stoa() might call std::__throw_invalid_argument("invalid argument for " + __name) (using a valid syntax of course).
