Bug ID: 21133
Summary: Readelf doesn't work about malformed ELF
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: zidsoft at gmail dot com
Target Milestone: ---

Testcase elf
It's possible to create an ELF file that readelf will perfectly read, but isn't
valid according to the spec, this later caused some confusion when ld tried to
link it against something.
I spoke with Alan Modra to figure out what was going on with the attached
testcase I was given, and he informed me the ELF has a local after a global in
the symtab, which is not allowed.
Would it be possible to get a warning added to readelf for this? I had assumed
if readelf could understand it that the ELF was proper. It along with nm
slightly misleadingly suggest that _start is a valid global symbol, when ld
will silently ignore it.
