The segv must be produced however it must be hidden by the kernel by
sending a SIGSEGV to kaffe (which looks like doing as kaffe runs after
the message).

The only possibility if you cannot disable the message printed by the
kernel is to disable stack detection and use another heuristic. However
we are not providing heuristic change at configure time.

Also, are you using glibc ? If it's the case we may avoid using the segv
handler to detect stack. 

Be aware that we are also handling some NullPointerException through the
sigsegv catching and so may get some of these for incorrectly written
java program.
