Hi all,
Since Dwarf 3 the length of a DW_FORM_ref_addr entry is not dependent on
the pointer size of the target platform, but on the used Dwarf-format
(32 bit or 64 bit) for the current compilation section.
When I load a project with Dwarf-3 debug information with fsf-gdb head,
it works. But not with the archer-jankratochvil-fedora13 branch. That
version assumes that the length of a DW_FORM_ref_addr on 64 bit is
always 64 bits, which is not the case.
Is it planned to merge this fix from fsf-gdb to
archer-jankratochvil-fedora13? How is this normally handled?
Regards,
Joost van der Sluis.

This is a HEAD patch

in DWARF 3 and later.
(read_attribute_value) <DW_FORM_ref_addr>: Likewise.

It works with FSF GDB HEAD, FSF GDB 7.1 and Fedora-13 gdb-7.1.
It does not work with archer-jankratochvil-fedora13 as it is just an
intermediate step for Fedora-13 gdb-7.1.
Tried now to merge archer-jankratochvil-fedora13 with gdb_7_1-branch but there
is a problem it would need changes for the FSF-accepted using-directive
patchset. One cannot cheerry-pick the patch as diff against gdb_7_1-branch
would then clash on that patch duplicity with FSF 7.1 release.

archer-jankratochvil-fedora13 is now probably completely frozen (=dead) as
I already add rather patches directly to the F-13 CVS. One cannot change F-13
much as it is far in its release cycle.
There should be some archer-jankratochvil-fedora14 branch created soon
(=roughly in about two months). I have to admit there is currently no fresh
Archer-merged branch.
Thanks,
Jan

Thanks for the information. As long as this problem is not in Fedora-13
I'm happy.
I can work around this for now. Thanks for the information.

Joost.
