Martin Sebor commented on STDCXX-664:
-------------------------------------
I think the dynamic cast patch
(https://issues.apache.org/jira/secure/attachment/12371623/stdcxx-664-1.patch)
might be a good idea in any case. I was going to add that we might also want to
throw in a conditional for _RWSTD_NO_THREAD_SAFE_EXCEPTIONS but I see it's
already there. It would be nice if they were both handled the same way. I've
modified your patch slightly and added some changes of my own to handle both
cases consistently: http://svn.apache.org/viewvc?rev=604088&view=rev
Btw., now that I've committed it I have a question for you about the comment in
the _RWSTD_NO_DYNAMIC_CAST block:
// if dynamic_cast isn't supported, then [has,use]_facet()
// can't reliably detect if a facet is installed or not.
test_has_facet() doesn't use opt_no_exceptions. Should it? Or is the mention of
has_facet in the comment not intended to relevant to the test function?
As for the other patch, I'm still undecided... But since the already committed
patch should fix the problem with the test (it no longer aborts) I think we can
close this issue and treat the question of using -qrtti=dynamiccast as a
separate issue.
