When building GCC w/o bootstrap I see that libcody properly sets -fno-rtti:
g++ -std=c++11 -g -O2 -fno-enforce-eh-specs -fno-stack-protector
-fno-threadsafe-statics -fno-exceptions -fno-rtti

Well, that is a fix for the bootstrap-ubsan issues, but not the above small
testcase showing the problems for users.
But sure, as this is a problem that exists many years and nobody reported it
before, it

I've got it!
It can be fixed with -fno-rtti and apparently libcody's objects do miss that :)

There's a self-container test-case:

class Resolver {
int GetCMIName();
virtual char GetCMISuffix() { return 'c'; }
};
int Resolver::GetCMIName() { GetCMISuffix(); return 0; }

That is not really possible, as the compiler assumes for
-fno-sanitize-recover=vla that when we call the library routine, it never
returns (it is noreturn).

I would recommend changing just libsanitizer to allow something like
UBSAN_OPTIONS=vla_bounds_allow_zero=1. Should be relatively small change.

I'd say it is similar with shifts, the diagnostics about the shift count being
negative or too large is highly useful, the diagnostics about the various
lshift properties shifting into sign bit or shifting

Fair enough. But there is also no way to selectively turn it off (or I am not
aware of it). The warning for < 0 is important and useful while the warning
for == 0 is pedantic and not useful by itself when

--- Comment #2 from Jakub Jelinek ---
The sanitizers generally diagnose what the C or C++ language spec say, not what
the various extensions allow, it is the same also for shifts etc.
So I think it is correct that this is diagnosed by default.
