RE: [Caml-list] Cygwin ocaml crashes

[Dave Berry]

My experience of Cygwin, when working at Harlequin, is that it was very
flakey.  New versions would fix earlier bugs but introduce new ones, and
versions would be incompatible.  I was rather hoping that this would have
improved by now.  We ended up keeping a known working version stored
locally, and always using that, if necessary patching it ourselves.
Fortunately this was all for internal tools, and we never had to worry about
distributing them.

Is it possible for INRIA to distribute the exact version of Cygwin needed
for OCaml?  I remember Cygwin having fairly nasty licensing restrictions.

I didn't get that kind of behaviour using the pre 3.01 cygwin-versions.
Maybe the error isn't that you need the latest cygwin,
but the same cygwin that was used to build ocaml. (I used the
binary installs.)

Hi,

I have the same problem (segmentation fault, STATUS_ACCESS_VIOLATION) using labltk;
I compiled ocaml 3.01 on the new cygwin 1.1.8-2. I don't have the problem of
undefined function, this works well :

$ ocaml.exe
        Objective Caml version 3.01
# fdas
  ;;
Characters 0-4:
Unbound value fdas
#quit;;
$

but when I use labltk (see the file ihm2.ml), the program crashs when I try to
erase the canvas.

Yes, downloading and rebuilding helps. The below, before and after:

BEFORE (cygwin-binary downloaded from www.ocaml.org):

data$ ocaml.exe
        Objective Caml version 3.01

# fdas
  ;;
      0 [main] ocaml 1604 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
  80086 [main] ocaml 1604 stackdump: Dumping stack trace to
ocamlrun.exe.stackdump
bash: [1516: 1] tcsetattr: Not a character device
Segmentation fault (core dumped)

AFTER (source downloaded and compiled locally using very up-to-date cygwin):

data$ ocaml.exe
        Objective Caml version 3.01

# fdas
  ;;
Characters 0-4:
Unbound value fdas
# #quit;;
data$

Hi,

I guess I went too fast sending my message yesterday. I had rebuilt a
cvs Ocaml on a couple months old cygwin and it did not work. Then I
got a new cygwin and it still did not work. This morning I rebuilt
Ocaml on the new cygwin and it does work.

RE: [Caml-list] Cygwin ocaml crashes

[Mattias Waldau]

I also get it, essentially the toplevel always crashed when you
get some kind of type-error or undefined. Note below that the
function 'g' isn't defined.

I run the latest cygwin (since it is so easy to update, just run
setup.exe again and it updates the necessary parts).

I didn't get that kind of behaviour using the pre 3.01 cygwin-versions.
Maybe the error isn't that you need the latest cygwin,
but the same cygwin that was used to build ocaml. (I used the
binary installs.)

You could try to download the source and recompile it locally.

Hi Alan,

thanks  for your reply. The toplevel also chrashes when I use it directly.
I downloaded and installed the latest  cygwin version. But the toplevel
still chrashes when using an undefined symbol.

Re: [Caml-list] Cygwin ocaml crashes

[Alan Schmitt]

Hi again,

It seems there is something that does not work anymore. I also get a:

    0 [main] ocaml 225 handle_exceptions: Exceptions: STATUS_ACCESS_VIOLATION
31220 [main] ocaml 225 stackdump: Dumping stack trace to ocamlrun.exe.stackdump
Segmentation fault (core dumped)

Any kind of error will do that (parsing, typing ...)

I'm using current cvs version of ocaml, and latest cygwin (1.1.8) on winNT.

I also had this problem (using the toplevel in cygwin, not emacs), and

[Caml-list] Cygwin ocaml crashes

[wester]

Hi,

I downloaded the CYGWIN version of OCaml301 and started the
toplevel in Emacs. But when using an undefined value (what occasionally 
happens) the program crashes. See below the Emacs output of ocaml:

        Objective Caml version 3.01

# 1+2;;
- : int = 3
# let f x = x*x;;
val f : int -> int = <fun>
# f 3;;
- : int = 9
# g 3;;
      0 [main] ocaml 129 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
  47809 [main] ocaml 129 stackdump: Dumping stack trace to ocamlrun.exe.stackdump

Process caml-toplevel exited abnormally with code 232192

Is it possible to avoid this?
