In the unit_name_replace_instance function in the src/shared/unit-name.c file, the pointer variable p is checked against NULL after it is used in a pointer difference. This triggers undefined behavior. In addition, the else branch of the if statement refers to the (meaningless) pointer difference: p = strchr(f, '@'); ... a = p - f; if (p) { ... } else { r = new(char, a + strlen(e) + 1);
Fixed in git.
