Bug ID: 20537
Summary: Do not fail on overlapping FDEs in .eh_frame_hdr
Product: binutils
Version: 2.27
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: raspy27 at gmail dot com
Target Milestone: ---
Please provide possibility to not fail on .eh_frame_hdr overlapping issues
and/or provide --no-eh-frame-hdr option.
My use case: I have code which needs to link to some 3rd party libraries. When
linking with those libraries, final link ends with fatal error:
/usr/bin/ld: .eh_frame_hdr refers to overlapping FDEs.
/usr/bin/ld: final link failed: Bad value
I have read through [1] and I have also seen bug 17467. I understand that the
issue is originally caused by GCC and I have verified that new version of GCC
and binutils work smoothly when using ld -r. Trouble is that those 3rd party
libraries are compiled with an old toolchain that manifested bug 17467 and we
cannot recompile the library.
I have verified that skipping --eh-frame-hdr makes linking succeed. However,
current GCC always automatically adds --eh-frame-hdr on linker call and there
is no --no-eh-frame-hdr option to override that. It would be good if such
option could be provided or the error could somehow be made a warning instead.
It seems that patch from [1] did not end up in the trunk, so the
-noinhibit-exec option does not seem to work around this issue.
