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:

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

This must be the first time that I'm unhappy because context doesn't 
fail. I try everything I did the other day to make the document break, 
but it still compiles like there had never been any problem...
