[PATCH] - fix segfault in decode_rtx_const for vector consts
- From: "Igor Shevlyakov" <igor at microunity dot com>

- Subject: [PATCH] - fix segfault in decode_rtx_const for vector consts
- Organization: Microunity
decode_rtx_const segfaults on non-zero vector consts because
value->un.addr.base is overriden by CONST_VECTOR and means nothing in
that case.
Solution is not to check it not only for RTX_DOUBLE but for RTX_VECTOR
as well.
