Binutils-2.29 invalid free()

[Pierre Muller <pierre at freepascal dot org>]

i386-darwin-as
is a cross-assembler
on gcc20 (linux x86_64 machine)
from GNU binutils version 2.29
configured with --target=i386-unknown-darwin  --disable-intl --disable-libtool

CFLAGS="-gdwarf-4 -O0"

I have no clue why qsort() generates a problem here ...
Is this a known issue?
