[MLton-user] Exception history

[andrew cooke]

Hi,

I think I'm missing something obvious.  I've enabled exception history
with -exn-history true while compiling, but am only seeing one level in
the history (the lowest, which is not a top-level function).  How do I get
a full stack trace?

This happens whether I let the runtime system print the history, or if I
print it myself with, for example:
main ()
handle e => ignore (map print (MLton.Exn.history e));

Which gives (just):
StringListDot.sml 11.27
which is certainly where the exception is raised, but doesn't include, for
example, main() itself.

The compiler was built from a recent CVS (should it print the version
below?), but I'm pretty sure I saw the same behaviour earlier with the
current release.

Thanks,
Andrew
