Hello,
today I updated lmtx and on simple

    $ context --version

I get segfault (in the same time luametatex --version works fine).
Running under gdb shows me that the problem might be in one of 'realloc'
calls.

The context from Context Suite (mkiv) works fine.

P.S. I tested on two systems, both runs Archlinux x86_64.
can you completely wipe the texmf-cache directory and then run

mtxrun --generate
context --make

(there is a change in bytecode that gets not automatically noticed that
can give that crash)

I had the same issue and completely wiping the texmf-cache fixes it.

@Vladimir: If you are using the luametatex package from AUR, then the
texmf-cache is located at $HOME/.cache/luametatex.

I'm receiving the super helpful error message:

     ! error (lua): function call: no

there is not much context to present there as it means that deep down a bad function token is expanded, something under control of the macro package, which then has/is messed up

Maybe some sort of cache versioning is in order to at least give a better error.

for now, adding

\ifdefined\pdfsavepos\else
    \let\pdfsavepos \savepos
    \let\pdflastxpos\lastxpos
    \let\pdflastypos\lastypos
\fi

to cont-new.mkiv seems to work ok
