Actually, there is a code in strace.c (main -> terminate() ) to raise the signal which killed the traced process. Strace does it exactly before exit
https://github.com/strace/strace/blob/1d98b287a4cb6901d369d78126d481508f9e35ef/strace.c#L2655

	if (exit_code > 0xff) {
		...
		/* Child was killed by a signal, mimic that.  */
		exit_code &= 0xff;
		signal(exit_code, SIG_DFL);
		...
		raise(exit_code);
	...
	exit(exit_code);

Code was added in 2008-09-29 commit
