BTW output the code with some markup 1 is a nice idea, but apparently, it does the attached output unreadable in Redmine :/ Therefore please check the ruby-core:89812 if the output is not readable for you.

Redmine can be a bit annoying. In that case it may have been possible
to perhaps write the initial code with proper indent, and add the
tests in a reply to it - but feel free to ignore this comment. It is
your issue request after all, not mine. :)
(I put the initial code next, just if someone wants to read it with
colours + indent):
def catch_true(paths, prefixes) # catch_except_p: TRUE
prefixes.each do |prefix| # catch_except_p: TRUE
paths.each do |path| # catch_except_p: FALSE
return path
end
end
end
def wrapper(paths, prefixes)
catch_true(paths, prefixes)
end
print wrapper(['1'], ['2'])
Edit: Strange ... the indent appears but not the colours. I wonder if
I did something wrong or whether something in redmine does not work;
I could swear that always used to work with four leading space ' '
characters ...

I'm not so familiar with redhat-hardened things. I have some questions:
- Why are you using the "hardened" options? Is it default on your environment?
- Do these tests succeed if you strip the hardened options on the same environment?
- I downloaded the files in your link, but my
./configure CFLAGS="-specs=/tmp/redhat-annobin-cc1 -specs=/tmp/redhat-hardened-cc1" DLDFLAGS="-specs=/tmp/redhat-hardened-ld"failed and I couldn't reproduce your issue on my x86_64 Ubuntu. Should I use another Linux distribution to reproduce your problem?

It is the default and mandatory settings for the build of all packages on Fedora/RHEL. The last hardening changes were proposed here:
https://fedoraproject.org/wiki/Changes/HardeningFlags28
Not sure if there is better documentation.
- Do these tests succeed if you strip the hardened options on the same environment?
Good question. It should be easy to disable the hardening. I'll try that.

Not sure. I guess the Annobin is Fedora specific stuff introduced in F28:
https://fedoraproject.org/wiki/Changes/Annobin
The rest should be quite generic with recent enough toolchain.
I am working with Fedora Rawhide, trying to prepare updated Ruby package, but Fedora 28 and newer should probably behave similarly.
Thx for looking into this issue.

Could you try eliminating -fstack-protector-strong?

and possibly -fasynchronous-unwind-tables -fstack-clash-protection as well
Updated by vo.x (Vit Ondruch) almost 6 years ago
It seems that -fcf-protection makes the difference. IOW this makes the test (specifically testing with test_lambda_longjmp) fail:
CFLAGS="-fcf-protection" \
CXXFLAGS="-fcf-protection" \
LDFLAGS="" \
FFLAGS="" \
FCFLAGS="" ./configure

Just confirmed that removing just -fcf-protection from the initial flag set makes the test pass.
Updated by k0kubun (Takashi Kokubun) almost 6 years ago
- Subject changed from TestJIT#test_{catching_deep_exception,compile_insn_throw,lambda_longjmp} segfaults to TestJIT#test_{catching_deep_exception,compile_insn_throw,lambda_longjmp} segfaults with gcc-8 -fcf-protection
Cool, thanks a lot. It looks like a new option of gcc. I reproduced your issue with:
./configure CC="gcc-8" CFLAGS="-fcf-protection"
I'll think about how to deal with this.

Here is the result of GitHub Actions on Ubuntu focal. The used configure options are ./configure --enable-shared --with-gcc="gcc -O2 -fcf-protection -Wl,-z,now" here. https://github.com/ruby/ruby/pull/5900#issuecomment-1126570348
