I'm not in a position to do much about things until week after next:
personal emergency. Do whatever you think is appropriate to mitigate
the problem.

It will probably boil down to an exception causing a debugger, and
since Squeak's command line support is... not adequate, it's
impossible to debug without someone manually running the same process
on a local machine, hacking the build scripts to run headfully. This
has been my experience, at least, whenever we have had this problem.

If someone's sufficiently motivated, they should be able to follow the
instructions at https://github.com/squeak-smalltalk/squeak-ci/ (and
hit me if they're not) and run something like "rake clean build
test_package[Control]" to reproduce the issue. You'll need to edit
lib/squeak-ci/build.rb replacing the vm_args method with this:

def vm_args(os_name)
  [] # Force headful
end

Only bother if you're comfortable with installing a Ruby. Diagnosing
and solving the problem will require more knowledge about process
spawning and subshells than I possess. run_image_with_cmd is almost
certainly the source of the problem:
