Re: [tz] [PROPOSED 1/7] Avoid undefined behavior if no Link lines

The core dump occurred because GCC translates this:

qsort(links, nlinks, sizeof *links, qsort_linkcmp);

as if it were this:

if (nlinks == 0) __builtin_trap(); qsort(links, nlinks, sizeof *links, qsort_linkcmp);

Right, so they are actually going out of their way to make it a gotcha. What point does that serve? regards, tom lane
