The function sigdescr_np is supposed to "return the message describing the signal signum" [1].
However, for the value SIGEMT, it returns a string without real information. If a user did not know what SIGEMT means before, he won't know it afterwards. How to reproduce: $ gcc -Wall foo.c $ ./a.out SIGEMT -> EMT trap Suggestion: Use the description string "Instruction emulation needed" instead. That's what is understandable from the FreeBSD man page [2]. Seen on Debian GNU/Hurd, with glibc 2.34.
