Just copy what *all* the other testcase in the library testsuite have,
just define it, with attribute unused. If you are curious why, just look
inside testsuite_hooks.h
3- We definitely need a comment explaining *who* provided _M_range_check
Sorry, I don't understand this suggestion.
You are right, sorry, I went through your changes too quickly and didn't
realize that you are just using the existing _M_range_check. Anyway, I
confirm that probably we want something more consistent with debug-mode,
thus not throwing in this case. Maybe just a __builtin_abort(), I don't
know. Or adjust the code in c++config to make available a non-trivial
__glibcxx_assert also when _FORTIFY_SOURCE > 0.
4- Maybe I'm misremembering, sorry in case, but Isn't:
#if defined _FORTIFY_SOURCE && _FORTIFY_SOURCE > 0
the same as:
#if _FORTIFY_SOURCE > 0
?
I think you're right, but I'm just copying literally what GNU libc is
doing. I can change it to the shorter version if you want me to.
I think we should yes.
