Bug ID: 28138
Summary: [2.37 Regression][bisected] Linker plugin complains
about "malformed archive" on thin archines
Product: binutils
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: slyfox at inbox dot ru
CC: hjl.tools at gmail dot com
Target Milestone: ---
Initially noticed as a nodejs-14.17.3 link failure against
gcc-HEAD+binutils-2.37 on x86_64-linux.
I did not manage to extract minimal example yet, but was able to bisect
binutils down to seemingly relevant
commit 7a30ac441a4e776e68399cb916c4731b5192e931

ld: Check archive only for archive member
Since plugin_maybe_claim calls bfd_close on the original input BFD if it
isn't an archive member, pass NULL to bfd_plugin_close_file_descriptor
to indicate that the BFD isn't an archive member.
bfd/
PR ld/18028
* plugin.c (bfd_plugin_close_file_descriptor): Check archive
only of abfd != NULL.
(try_claim): Pass NULL to bfd_plugin_close_file_descriptor if
it isn't an archive member.
ld/
PR ld/18028
* plugin.c (plugin_input_file): Add comments for abfd and ibfd.
(plugin_object_p): Set input->ibfd to NULL if it isn't an
archive member.

collect2: error: ld returned 1 exit status
The special thing here is lib*.a thin archives, built as:
x86_64-pc-linux-gnu-ar crsT
/dev/shm/portage/net-libs/nodejs-16.5.0/work/node-v16.5.0/out/Release/obj.target/tools/v8_gypfiles/libv8_compiler.a
/dev/shm/portage/...
I'll attach full build.log if it's of any help to craft artificial example.
