Although MLton does understand about running out of memory (when an `mmap`
request fails), on recent versions of Linux, I've observed that the OOM
killer will sometimes step in before a failing `mmap` request. But, I
wouldn't think that that would manifest itself as a seg fault. In any
case, I

I can reproduce this even with the latest upstream HEAD on the hppa
porterbox, using
Don't know about amd64 or x86.
I tried adding "-codegen c" to MLTON_FLAGS but it didn't make any difference.
Gdb generates full backtrace with core file. Thus, in theory, it should be
possible to
debug. But without symbols, it's hard to tell what's going on.
The fault outside the chroot is
ssume that it isn't reproducible on AMD, right?
Or better, x86 (32 bit)?
One thing to try, under either of these, would be compiling stuff with
-codegen c
or, compiling the compiler with that.
The idea is that the HPPA stuff must use the C compiler back end.

Same issue with Linux overcommit turned off. The machine is not running out of
memory and
there is lots of swap (40G).
Don't really know what's causing segfault.

How do I do that?

If it isn't too hard, could you try it with Linux overcommit turned off?

Dear Maintainer,
Because of dependency problems mlton_20210117+dfsg-3 had to built
manually on hppa. However, it seems mlton_20210117+dfsg-3 cannot
rebuild itself on hppa.
