The stack trace is clearly incorrect:
void *
memchr(const void *s, int c, size_t n)
{
if (n != 0) {
const unsigned char *p = s;
do {
if (*p++ == (unsigned char)c)
return ((void *)(p - 1));
} while (--n != 0);
}
return (NULL);
}
Type "frame 9" and see what it says. If the bug is easily reproducable,
try reproducing it with a debugging version of libc (buildworld with
DEBUG_FLAGS=-g)
