[MLton-devel] MLton Install and Win32 port...

Hi Anoq.  I'm glad to hear your finally (sort of) settled.

Now is a good time.

Hmmm.  So this is a problem with an old MLton (you didn't say which
version -- one you made or a release) compiling the new one, right?
About all I can tell from the log that you sent is that the x86
codegen was almost done when the failure happened.  That doesn't say
much.  Maybe you could run -v2 and with strace to see what system call
failed.

Even an old MLton should be fine with 512M.

Especially if this is a problem with 20020923, please try to reproduce
it.  MLton apps should never crash (segfault), they should at least
report "Out of memory".

Yeah.  We can do self compiles on 256M machines now (too late for you,
since you've got 512M now).
