It certainly seems to shut up cppcheck, the static analyser.
Not sure how to get gcc or clang to detect this problem.
$ cat dec4a.cc
extern void g( const char *);
void
f( const char * start, unsigned long ul)
{
if (start + ul < start)
g( start);
}
$ ~/gcc/results/bin/gcc -c -O2 -Wall -Wextra -Wtype-limits dec4a.cc
$ ~/llvm/results/bin/clang++ -c -O2 -Wall dec4a.cc
$
