REPORT_CB/2 CRASH when single_line => false, chars_limit => 32768 #6591
Description
Describe the bug
logger logs REPORT_CB/2 CRASH when using formatter config single_line => false, chars_limit => 32768
To Reproduce
Run erl and evaluate two expressions:
> logger:set_handler_config(default, formatter, {logger_formatter, #{single_line => false, chars_limit => 32768}}).
> proc_lib:spawn(fun() -> ets:first(a) end).
Expected behavior
Crash report is formatted nicely
