Subject: [PATCH 1/3] sh: Set gd->malloc_base if MALLOC_F_LEN is set
Date: Sun,  2 Aug 2020 17:05:49 +0200	[thread overview]
Message-ID: <20200802150551.114604-1-marek.vasut+renesas@gmail.com> (raw)

The gd->malloc_base must be set before the C runtime if the MALLOC_F_LEN
is non-zero, otherwise we hit assertion in dlmalloc.c initf_malloc(). So
set it.
