Test failures on gcc 11
Description
There is gcc 11 (development version) [1].
On Fedora rawhide (Fedora 34), the gcc version is 11.0.0-0.7.fc34. I got 2 test failures on Fedora 34. The failures come from a warning -Wsizeof-array-div that is a new feature on gcc 11.
Here is the log.
+ make check 'TESTS=-v ' 'MSPECOPT=-fs -P '\''raises TypeError if one of the passed exceptions is not a Module'\'''
...
1) Failure:

Seeing the gcc 11 release note [2], it seems that the new warning -Wsizeof-array-div causes the failures.
C family
New warnings:
-Wsizeof-array-div, enabled by -Wall, warns about divisions of two sizeof operators when the first one is applied to an array and the divisor does not equal the size of the array element.
Here is the detail of the warning. [3]
Could you fix it? Thank you.

Thanks for the patch! Let me check it tomorrow!

Hello, I have encountered similar warnings in clang and had some fix at this commit https://github.com/ruby/ruby/commit/2366c681166a1dab95de6b9ca8ffcaae18aadd39
In case of clang adding parens suppress the warning. Doesn't this work for gcc as well?

Interesting, but I can't reproduce that warning with clang-{10,11} of Ubuntu and MacPorts.
/* conftest.c */
#include <stdio.h>
#include <setjmp.h>
int main(void)
{
printf("%zd\n", sizeof(jmp_buf)/sizeof(int));
return 0;
}
$ clang-10 --version
Ubuntu clang version 10.0.1-6
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
$ clang-10 -Wall -Werror=sizeof-array-div -c conftest.c && echo ok
ok
$ clang-10 -O3 -Wall -Werror=sizeof-array-div -c conftest.c && echo ok
ok

Anyway, if no warning against the line in vm.c, the same will work against RBIMPL_EMBED_LEN_MAX_OF macro.
Updated by shyouhei (Shyouhei Urabe) over 3 years ago
clang warns on this one, not sure why though.
https://gcc.godbolt.org/z/c7baPr
#include <stddef.h>
#include <setjmp.h>
struct foo_tag {
jmp_buf foo;
} foo;
size_t
bar()
{
return sizeof(foo.foo) / sizeof(int);
}

Does this work?
I tested with the patch. But no it does not work. Here is the log. Sorry for the long long.
I noticed the warnings appear at the timing of the make.
In the log the 1) Failure I see today might be not related to the gcc 11 issue.

Thanks! I will try the patch on Monday.
By the way, if you want to try gcc-11 on Ubuntu, I found gcc-11 on ubuntu-toolchain-r repo.

JFYI tests for various compiles in our CI suite currently stick to Ubuntu bionic (18.04) because this was the last release which shipped gcc 4.x. OTOH gcc 11 on Ubuntu seems hirsute (21.04) exclusive for now.
It seems someday we have to either drop old gcc or drop recent gcc. We have no bandwidth to maintain gcc binaries.
PS. This is not an issue for clang. I love how LLVM team provides every version they have to every OS they know.

I've tried autoconf 2.70 in these days, but couldn't compile with gcc 4.9.
So I think we may have to drop old gcc when shipping configure script generated by autoconf 2.70.

What are the advantages of switching to autoconf 2.70 compared to sticking with 2.69? OpenBSD uses gcc 4.2 on many older platforms where clang doesn't work well or work at all. I would hate to lose the ability to use Ruby on these older platforms. If there are substantial benefits to autoconf 2.70, and it isn't possible to achieve those benefits with autoconf 2.69, maybe the benefits outweigh the costs. I'm just not sure what the benefits are.

I don't claim we should switch to 2.70 (at least now), but we'll need to be 2.70-ready.
It may be necessary when the platform used by release managers does so in future, but it is not the case now.

I see. Thanks for the info. My hope is that people in ubuntu-toolchain-r will add gcc-11 for older platforms in near future, as gcc-11 is still in development for now. My another hope for gcc-11 to support the older platforms is the one from Debian side, for Ubuntu to pick up.
It's only available on the experimental repo.
https://tracker.debian.org/pkg/gcc-11
For our CI, I assume you are talking about .github/workflows/compilers.yml, right?
Can not we select os in the matrix of compilers.yml? If we can we can be available gcc-11 on a newer Ubuntu version. I am still not familiar with GitHub Actions syntax.
PS. This is not an issue for clang. I love how LLVM team provides every version they have to every OS they know.
Oh it's cool. Though I am not sure which page you see for the "how LLVM team provides every version they have to every OS they know", I can see the official LLVM site provides clang-11 on Ubuntu 20.04 and 16.04.
