Bug #17574: Hash#inspect segfault

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]
• Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN

[01wsmith (w smith)]

While working in irb, I encountered an issue:

x = {1 => {2 => 5}, 3 => {4 => 6}}
y = x[1]
y[11] = 3
x.transform_values!(&:clone)
y[11] = nil
x

x.inspect causes irb to segfault.

I was not able to test this on ruby 3.0.0.
While experimenting with this I found that x[1] may change.
However, it seems to work fine in ruby itself.

irb -v: irb 1.2.1 (2019-12-24)

I failed to reproduce this. Could you report your entire command logs and SEGV output to see a backtrace?
