Hi Jonathan!
It seems, that the minor change/fix from comment #31 (rev. 245505) is currently
missing in branches/gcc-6-branch/libstdc++-v3/src/c++11/snprintf_lite.cc; needs
also to be merged into this.

Hi!
There's a minor failure in the (patched) function __concat_size_t (within
snprintf_lite.cc):
size_t __len = __out - __cs;
Calculates the remaining/unsused characters in the buffer __cs!

Hi!
@Jonathan:
Do you have any plans to backport/migrate these changes to the GCC 5 and/or 6
branch, to be provided/included on a next release?
An "official" fix would be much better (C++-development on

Hi!
My motivation to use/implement this patch (comment #6) is to prevent using
malloc to allocate the needed emergency-buffer region, if the needed overall
size is bellow a (configurable) limit; e.g., emb

I do not (completely) agree, that the code/result is undefined. Of course, this

At least this error is based on some libintl-macros, which will "redirect" some
stdio-functions (like vsnprintf ...) to their libintl-version(s); I.e. the
