There are expected segfaults in libjvm?
Sorry, I am 100% ignorant about this subject. I just wanted to know if
that was the intended meaning.
Yes there is a deliberate segfault during VM startup to check AVX
register save/restore behaviour. An optional one (non-product) for APX
register save/restore behaviour.

I can't comment on the rest of your message, but I might be able to
help
with
this. The JVM sometimes executes code that may trigger signals that are
expected to be handled by the JVM's signal handler. In particular, I
know
there are a couple of these early in startup. Just try continuing in the
debugger, and let the JVM's signal handler have a crack at them. If
it's one
of the expected ones, things will proceed normally.
