Bug ID: 21939
Summary: Binutils-2.29 invalid free()
Product: binutils
Version: 2.29
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: muller at sourceware dot org
Target Milestone: ---
Created attachment 10334
--> https://sourceware.org/bugzilla/attachment.cgi?id=10334&action=edit
system.s source (renamed because of transfer necessities)
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 ...
