This is a serious bug in objcopy in the current binutils. Given that
cygport creates the debug info automatically, we might end up with
spuriously broken DLLs in the distro.
we already have some :
/usr/bin/cygcrypto-1.0.0.dll
8 .gnu_deb 0000001c 67542000 67542000 0017ac00 2**2
/usr/bin/cyglsa.dll
6 .gnu_deb 00000014 10007000 10007000 00001400 2**2
/usr/bin/cygssl-1.0.0.dll
8 .gnu_deb 0000001c 58fcf000 58fcf000 00059a00 2**2
I checked every /usr/bin/*.dll on my system (which is a lot), and these
three, plus cyglsa64.dll (which can only be read by
x86_64-w64-mingw32-objdump), are the only ones which show this. I did
manage to reproduce this on my machine with openssl, and passing
--long-section-names=enable to objcopy does fix this, but why are only
these DLLs affected?
Don't forget Marco's DLLs. However, aprt from that it's kind of weird
that all of them are built by me, isn't it? I just don't see where
the connection is. I'm using your stock Fedora cygwin tools on Fedora 17
to build the Cygwin DLLs. OTOH, the openssl package doesn't support
cross builds, so I'm using stock Cygwin distro gcc, binutils, and cygport
to build openssl.
This is quite puzzeling.

No clue what is causing rebase to chock. I compared the
".reloc" section of
built, stripped and with debug link versions of dict_snowball.dll,
and I did not notice any difference (but I am not a PE-COFF expert)
all file here:
http://matzeri.altervista.org/works/rebase/
Please note that rebase segfaults on dict_snowball.dll the first time
but any subsequent rebasing, also with different start address,
works without any problem, so it is possible that we had other
dll with the same problem but we never noticed
I already explained why: The SEGV happens during relocation.
The file header has been changed already. If you call the
same rebase, it will try to rebase the file to the same new
address. If current file base address == requested file base
address, rebase will return without performing any action.
I was not clear.
Also rebasing with a different address make no difference
