Florian Weimer 0d50f477f4 stdio-common: Handle -1 buffer size in __sprintf_chk & co (bug 30039) ... This shows up as an assertion failure when sprintf is called with a specifier like "%.8g" and libquadmath is linked in: Fatal glibc error: printf_buffer_as_file.c:31 (__printf_buffer_as_file_commit): assertion failed: file->stream._IO_write_ptr <= file->next->write_end Fix this by detecting pointer wraparound in __vsprintf_internal and saturate the addition to the end of the address space instead.
