Failing to intercept something may cause not just false negatives, but

These cases are often exceptionally hard to debug, so any checking that
the interception machinery works as intended is good. Of course if
these checks are wrong we should fix them.
But at least don't report anything when the program starts, but at the
end of the ASAN failure report (if anything has been detected).
Like:
WARNING: libasan.so.1 isn't early in the symbol search scope, some symbols
in it might be interposed.  Try LD_PRELOAD=libasan.so.1.

or so.
Yes please. For me, and I don't think my setup is such uncommon, the noise is quite annoying.
