I'm attaching the zipped directory that adareducer left after dying. I'll upgrade adareducer to its most recent version and try to figure out where this is coming from.

I had a go at it but need uwrap.gpr:2:06: imported project file "libtemplatelang" not found uwrap.gpr:3:06: imported project file "libtestlang" not found

[glacambre]

Right, sorry, you also need to run source env.sh before attempting a reduce. And you might actually need to go through all the steps in the README :/. Uwrap is a pain to work with, don't force yourself to delve into that :)

[setton]

okay, it's running now. Do you have the source file on which this appeared, by any chance, to speed it up?

[glacambre]

I don't (I lost the output of my command, sorry). However I was left with a src/wrapping-runtime-structure.adb.crash file (which is available in the zip file). Could that be the one?

[setton]

I'll try!

[setton]

So, after a lot of processing, I can reproduce - not exactly this, but an inconsistency after processing a file. I'll need to add a master debug mode to understand what's happening.
