squeak - Illegal instruction (core dumped) when run on FreeBSD 10.1-RELEASE i386

Attempting to run

$ squeak Squeak4.3.image

on FreeBSD 10.1-RELEASE i386
results in

Illegal instruction (core dumped)

This happens both when squeak is installed from the binary package:

# pkg install squeak

and when it is compiled and installed from ports with default settings:

# cd /usr/ports/lang/squeak
# setenv BATCH yes
# make install

As a workaround, I can get an i386 squeak version that works by
compiling and installing from ports with compiler optimizations disabled
like this:

# cd /usr/ports/lang/squeak
# setenv BATCH yes
# setenv CFLAGS -O0
# make install

or with debugging info:

# cd /usr/ports/lang/squeak
# setenv BATCH yes
# setenv WITH_DEBUG yes
# make install

Also, squeak runs normally on FreeBSD 10.1-RELEASE amd64.

Any ideas how to fix the i386 version?

Or how to modify the squeak port so that it compiles the i386 version
with CFLAGS set to -O0 by default so that the binary package works out
of the box?

Steps to reproduce the issue are below.

Best Regards,


This is how you can reproduce the issue on
- real i386 hardware and/or
- VirtualBox
on a clean install of FreeBSD 10.1 i386.

FreeBSD version info:

# uname -a

FreeBSD fbsd1 10.1-RELEASE FreeBSD 10.1-RELEASE #0 r274401: Tue Nov 11
22:51:51 UTC 2014
root at releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  i386

Install the binary squeak package:

# pkg install squeak

Copy the squeak image and changes file to the current directory:

$ cp /usr/local/lib/squeak/Squeak4.3.image .
$ cp /usr/local/lib/squeak/Squeak4.3.changes  .

Run squeak:

$ squeak Squeak4.3.image

CHECKING squeakvm
Illegal instruction (core dumped)

This will have created a core file.
Please note that the creation of the core file can take several minutes
on slow hardware as its size is over 1GB. While creating the core file
the squeakvm process is unkillable.
