Segfault when using `setelement` and `erlang:system_time`

[giacomocavalieri]

Describe the bug Running the following code results in a segmentation fault:

-module(wibble).
-export([a/0]).

a() ->
    C1 = {erlang:system_time(), true},
    C2 = erlang:setelement(2, C1, false),
    C3 = erlang:setelement(2, C2, false),
    b(C3).

b(_) -> erlang:error("crash!").

To Reproduce Compile and run the code:

1> c(wibble).
{ok,wibble}
2> wibble:a().
[1]    56687 segmentation fault  erl

Expected behavior I'd expect to see the exception and not the shell to die with a segfault

Affected versions

• Erlang/OTP 26 [erts-14.2.5] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit] [dtrace]

Additional information I've asked others and it looks like this only happens on macOS with OTP26, while OTP27 doesn't have the same problem

Thanks for your report, and sorry for taking so long to start working on it. I've fixed it in #8898 :-)

No problem at all, thank you so much! 💜
