Hi,
I haven't yet been able to reproduce this in a minimal example, but I'm
trying to place some images within a mixedcolumns environment, and I get
an error message I have never seen before:

mtx-context | fatal error: no return code, message: luatex:

This is with context 2014.03.28 15:04 and luatex 0.78.2 on linux 64-bit.
The error does not appear with a beta version from january 2014. Any
idea where this might come from?
Thomas

Ok, we need indeed some example of this so that we can test. It can for
instance relate to some prev pointer still not being ok (which can
result in such errors). This means that when context looks back at some
node that happens to be a head node, we can get weird effects. In due
time this will be sorted out but the more tests we have the sooner.

Sadly, it is a Heisenbug - I have been unable so far to isolate it.
Compilation showed this bug both on linux and OS X - commented parts of
the file in question - compilation worked - uncommented line by line -
compilation keeps working without error. I'm no longer sure if it is
indeed a problem with the mixedcolumns environment or the new
bibliography code or a combination of both...

no, it's one of those ransom issues where a pointer is not set/reset
which needs to b esorted out in luatex itself
if you put the test file that fails in the crited repos luigi and i can
run it and rather easily (less than a day work -) determine where it is
