Description

Here is the assertion...

..\..\..\tests\src\printf.cpp:486: char *__cdecl _rw_bufcat(struct Buffer &,const char *,unsigned int): Assertion '0 == memcmp (*buf.pbuf + *buf.pbufsize, guard, guardsize)' failed.

Here is a testcase...

#include <rw_printf.h>
#include <string.h>
#include <stdlib.h>

int main (int argc, char* argv[])
{
    const char* s = 1 < argc ? argv [1] : "bug-zapper";

    char buffer [4];
    char *buf = buffer;

    size_t bufsize = sizeof buffer;

    rw_asnprintf (&buf, &bufsize, "%s", s);

    if (buf != buffer)
        free (buf);

    return 0;
}
