[Xerxes Rånby <xerxes@xxxxxxxxx>]

The java libjvm.so file contains an asm interpreter that defines a .init_array section in the libjvm.so
defined in the file cppInterpreter_arm.S:
http://icedtea.classpath.org/hg/icedtea6/file/0b656f7601bd/ports/hotspot/src/cpu/zero/vm/cppInterpreter_arm.S

this .init_array section makes dlopen execute initialization code for
the asm interpreter that seems to trigger the crash.
