Hi Kip,

I was afraid, that something like this could happen. On [1] I've put
a luametatex package, which is linked statically with mimalloc. Could
you try if it solves your issue?

Hilmar, just a shot in the dark here, but you might want to check to
see if certain CPU extensions were enabled at compile time, like AVX,
etc. SIGILL's are sometimes raised when the host machine hits an
instruction its CPU doesn't recognize but is found in the ISA of other
similar CPUs.


My one was just a a try too. The luametatex package (as it is) is now in the Debian archive for about 0,5 years and seems to be working. I see a timely correlation between the mimalloc upload and the luametatex crash. There could be a causal relationship....

Let's wait for test results from the submitter.
