|Summary||0003462: Crash with ocaml top-level when using Cygwin|
|Description||Full_Name: Janne Hellsten|
OS: Windows XP
Submission from: 126.96.36.199 (188.8.131.52)
I bootstrapped Ocaml with
./configure --prefix /home/janne/ocaml
When I run the Ocaml top-level from Cywgwin bash, I get a segfault with really
Objective Caml version 3.08.2
Segmentation fault (core dumped)
It appears that when it hits a syntax error, the whole top-level segfaults.
When I run the top-level from Emacs, everything works as expected (e.g., the
syntax error message is output properly).
The same thing happens with 3.08.1 as well.
When I run it through GDB, I get this
48 [main] ocaml 580 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
640 [main] ocaml 580 open_stackdumpfile: Dumping stack trace to
I have no idea what's causing it.
Just in case it's GCC related, here's the output of gcc --v:
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/specs
Configured with: /gcc/gcc-3.3.3-3/configure --verbose --prefix=/usr

--enable-interpreter --enable-threads=posix --enable-java-gc=boehm
Thread model: posix
gcc version 3.3.3 (cygwin special)

Yes, it crashes when trying to highlight the location of the error.
Several users reported this problem but we've never been able to
reproduce it. It seems to come from a bug in some versions of the
"curses" library provided by Cygwin. Upgrading Cygwin (and rebuilding
OCaml just to make sure) fixed the problem for at least one user.
A quick workaround is to disable error highlighting by invoking ocaml

This does not really bother me, I just wanted to report it in case it
had not been reported earlier. A note about Cygwin: it happened on two
different Cygwin installations, both relatively recent (the other one
installede from scratch yesterday, other ~week old).

|Recurrent Cygwin issue, probably with termcap/terminfo. Cannot reproduce.|
This problem has disappeared with more recent versions of Cygwin and OCaml (tested with 3.12.1 and 4.00.0 on a 2012-era Cygwin).
