1. crash_message() problem

Hi all,

when I run this program ...

include machine.e

crash_message("An unexpected error has occurred!"
            & "\nPlease send the file \"ex.err\" to <john_doe at whoops.com>.")

function add (atom a, atom b)
   return a + b
end function

? ad(1,2)

... Euphoria prints the following error message on the screen:
-=-=-=-=-=-=-=-=-=-=-=-=-
C:\Desktop\test.exw:10
ad has not been declared
? ad(1,2)
    ^
-=-=-=-=-=-=-=-=-=-=-=-=-
(tested with exw.exe 2.4 and 2.5 alpha).

But it should print my message instead, shouldn't it?

Regards,
   Juergen

If crash_message() is used only for runtime errors, then there is an
error in the documentation (Eu 2.5 alpha, lib_c_d.htm#crash_message):

<quote>
Description: Specify a string, s, to be printed on the screen in the
event that Euphoria must stop your program due to a compile-time or
run-time error.
</quote>

Maybe in 2.5 it only works with run-time errors, where this is a
parser/compile-time error.  That would seem to be more correct behavior anyway
(the 2.5 way)...

Thanks for checking it! I'm sorry, I must have made a mistake
previously. Now testing it again, on Eu 2.4 ex.exe and exw.exe actually
print my crash message.

Using Eu 2.5 alpha, I still get the original Euphoria error message
shown above. I also think that this probably might be "the 2.5 way".
In this case, IMHO the 2.5 documentation for crash_message() should
be changed accordingly.
