Bug ID: 24806
Summary: Linking with unclosed -start-group and -T init.ld
creates incorrect result
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: ohngeonocaewoungooth at xff dot cz
Target Milestone: ---
Created attachment 11906
--> https://sourceware.org/bugzilla/attachment.cgi?id=11906&action=edit
Tar file with files to reproduce the good/bad binaries
If I link with '-T init.ld' and a unclosed -start-group:
------------------------------------------
SECTIONS
{
.tools :
{
tool_entries = .;
*(.tools)
LONG(0)
LONG(0)
}
}
INSERT AFTER .debug;
--------------------------------------------
The tools section will be placed differently than if I don't use -start-group
or close it explicitly.
objdump -h prints:
--------------------------------------
bad: file format elf64-x86-64
Sections:
Idx Name Size VMA LMA File off Algn
0 .tools 00000020 0000000000000000 0000000000000000 00001000 2**0
CONTENTS, ALLOC, LOAD, DATA
... [snip] ...
--------------------------------------
good: file format elf64-x86-64
Sections:
Idx Name Size VMA LMA File off Algn
... [snip] ...
25 .tools 00000020 0000000000006060 0000000000006060 00003060 2**0
CONTENTS, ALLOC, LOAD, DATA
--------------------------------------
This leads to a non-working executable. I've attached a complete test case.
