Description of issue

First, this channel says "Casks" (binaries), but found no channel for "Formulae" (source). Move posting if applicable.

Ruby via Homebrew has an issue where SIGINT causes a crash. However, when compiling Ruby from the same date that the Homebrew version was released (or even way further back), there is no crash. Can anyone pinpoint the source of the error, or when can a non-crashing version be expected to be released?

Can you provide a minimal way to reproduce this?

[carlocab]

I can't reproduce a difference between Homebrew Ruby and one that I compiled myself:

# With Homebrew Ruby
❯ /opt/homebrew/opt/ruby/bin/ruby -e 'sleep' &
[1] 71930
❯ kill -INT $!
-e:1:in 'Kernel#sleep': Interrupt
	from -e:1:in '<main>'
[1]  + 71930 interrupt  /opt/homebrew/opt/ruby/bin/ruby -e 'sleep'

# With a self-compiled Ruby
❯ ~/.rbenv/shims/ruby -e 'sleep' &
[1] 72088
❯ kill -INT $!
-e:1:in 'Kernel#sleep': Interrupt
	from -e:1:in '<main>'
[1]  + 72088 interrupt  ~/.rbenv/shims/ruby -e 'sleep'

Thanks for reaching out. Try the oneliner on the duplicate: sparklemotion/nokogiri#3528

I can reproduce this with Ruby built from ruby-build, so it's not Homebrew specific. I'll respond in the other thread.
