> There are 2 uses of malloc. 1 is behind BOOST_CHARCONV_DEBUG used for printing 128-bit integer strings in ryu_generic_128. The other could in an extreme edge case be hit by the user. It is used in a fallback routine in case of unsuccessful 80 or 128 bit long double conversions in from_chars. If the conversion is unsuccessful on first attempt, and the string is more than 1024 bytes then we need to malloc to avoid a buffer overrun. The rationale for malloc is that it won't throw of failure.
Under which conditions would this happen? Could you please provide an example?
Thanks,
Ruben.
