* Exits process with crash report.

|
|
* The `cosmoaddr2line` command may be copied and pasted into the shell
|
|
* to obtain further details such as function calls and source lines in
|
|
* the backtrace. Unlike abort() this function doesn't depend on signal
|
|
* handling infrastructure. If tcsetattr() was called earlier to change
|
|
* terminal settings, then they'll be restored automatically. Your exit
|
|
* handlers won't be called. The `KPRINTF_LOG` environment variable may
|
|
* configure the output location of these reports, defaulting to stderr
|
|
* which is duplicated at startup, in case the program closes the file.
