Here's another bogus warning #20200. This one goes away if I drop +d,
or the first call to strchr(), or use s directly instead of assigning
it to ss in the for loop.

$ cat u.cpp && aCC -V -c +d +w u.cpp
#include <string.h>
char *s;
void foo () {
if (s && strchr (s, 'x')) {
for (const char *ss = s; *ss; ++ss) {
ss = strchr (ss, 'x');
if (!ss)
break;
}
}
}
