Bug ID: 64315
Summary: num_put misbehaves if the C library doesn't support
floats
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: ville.voutilainen at gmail dot com
In num_put::_M_insert_float, __convert_from_v can fail, leading into a __widen
being called with a negative size. This may happen with a C library that has a
sprintf that refuses to support floats and returns -1 when a float is used with
it.

If we can handle this without penalising the common case it would be nice to
fail politely, rather than crash in flames.
