Hi,

yes, dnsmasq has some stability issues. This has become way better
since a few releases, but it is still not at the level where it should
be.

Have you any information about how to reproduce the crash? I
experienced them for a time, but they were all random and I could not
debug this a lot.

I just merged a patch with some fixes. Maybe it has been fixed in
there. Please test Core Update 96 as soon as it becomes available for
testing.

Best,
-Michael
