[M3devel] crashes everywhere

[Rodney M. Bates]

I was unable to reproduce this m3gdb problem, but I looked at ways
this could happen.  In your case, m3gdb is getting  conflicting
information about whether it is debugging a program compiled by pm3
or cm3.

As a workaround, since we know (don't we?) that it is actually cm3,
and that agrees with what m3gdb thinks at the time of the assertion
failure, it is probably safe in this case to ignore the message and proceed.
You might even try the bt command again immediately.  This error should
self-heal at this point.

It would be helpful to me if you sent me the output of these commands:

objdump -G <your_executable> | grep MM__m3main
objdump -G <libm3core.so> | grep ObjectTypecell

Substitute the appropriate paths for your linked executable and wherever
it finds libm3core.
