I never finished my patch. I was hoping someone else would help finish it. Since it is my patch, I'll follow up on this. The first thing I did here is grep the entire tree for TREE_OVERFLOW (TYPE_SIZE (...)) since all such occurances are broken. I found 3. One in the C front end (this bug), one in the C++ front end, and one in the Ada front end. I can't create a testcase for the Ada bug, nor can I at the moment build the Ada front end, so there is not much I can do there other than maybe create a new bug report for it and insert the obvious patch. The C++ code is identical to the C code, so the same testcase and patch work here. Unfortunately, there is a problem. I get tmp.cc:13: error: size of array array is too large tmp.cc:17: error: array was not declared in this scope The first error is correct, the second one isn't. Or at least I assume it isn't. I'm not qualified to comment on that, nor am I qualified to fix it. So, um, I guess I am creating yet another new bug report for that. For the C front end, I have a patch that I believe is correct, and I have a small testcase that I think is reasonably portable. I need to drop my testcase into the testsuite with dg annotations, and test it all with a bootstrap and make check. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21105
