Seeing these failures only, when libffi is built with --enable-debug,
on powerpc-linux only. The bugs remain without the --enable-debug switch,
but are not triggered by the testsuite.

All failures have the form

    ASSERTION FAILURE: ../../../src/libffi/src/powerpc/ffi.c line 118

Looking at libffi/include/ffi_common.h, the assertion triggers, if the
macro argument is not properly aligned.

ffi.c line 118:
 /* Check that everything starts aligned properly.  */
  FFI_ASSERT(((unsigned)(char *)stack & 0xF) == 0);

The stack should be 16-byte aligned.  Probably the wrong one of the
multitude of stack alignment macros is being used.

Appended is the test-summery of libjava configured with --enable-debug.
