Hi Neels,

5.4.0 is rather old now. I assume Ubuntu has made some incompatible
changes to its kernel or C library interfaces that the old cm3 binary
cannot cope with. What about trying one the more recent installation
archives, like d.5.5.1? Once you have a working cm3 and cm3cg, compiling
the rest should be no problem. Stable releases cannot necessarily be
expected to run on newer operating systems when the ABI changes, as they
don't adapt themselves ;-)

Try this, for example:

http://modula3.elegosoft.com/cm3/snaps/cm3-min-POSIX-LINUXLIBC6-d5.5.1-2008-01-24-03-35-01.tgz

It should also be possible to get a backtrace of the cm3 crash
within gdb. There should be debugging symbols in the distributed
binaries. What does bt show?

If debugging symbols are missing, we've got to fix that.
