Hello Rafael.

Since we were observing a nondeterministic order in the invocation of 
callback ASTConsumer::HandleCXXImplicitFunctionInstantiation, we started 
searching the mailing list and bumped into this thread.

We downloaded and applied the two patches for clang and llvm: unless we 
did something wrong (e.g., out-of-date patches?), it seems that the 
nondeterministic behavior we were observing is still there.

We managed to produce a testcase on which clang (no matter if patched or 
not) generates multiple diagnostics in nondeterministic order.
The test is attached. Running it some 4/5 times should be enough to see 
the differences in the ordering of diagnostics.

Can you have a try on it?
Is this due to another, unrelated source of nondeterminism?

Enea.
