binutils-2.19.51.0.3.20090310
gcc-4.3.3

tested on i386-pc-solaris2.10, sparc-sun-solaris2.10, x86_64-unknown-linux-gnu:
===
x86_64-unknown-linux-gnu $ uname -a

"ar rc" seems to work fine on all platforms.

"ar t" seems to work fine on all platforms (output looks right).

"at tv" reports wrong permissions on i386-pc-solaris2.10 / sparc-sun-solaris2.10!

"ar xv" extracts invalid archives with wrong permissions on i386-pc-solaris2.10
/ sparc-sun-solaris2.10!

... could be an endian issue ...

this bug causes issues when compiling programs that create and extract archives
during their compile process (recognized with gcc-4.3.3 and libX11-1.2 -->
impossible to compile with binutils-2.19.51.0.3.20090310 on i386-pc-solaris2.10
/ sparc-sun-solaris2.10).

things seem to be fine with binutils-2.19.50.0.1.20081007,
but fail on 2.19.51.0.1.20090106 and 2.19.51.0.2.20090204.

will attach test directory

Comment 2 Niki W. Waibel 2009-03-24 16:37:02 UTC 
i meant to say:
===
"ar xv" either fails to extract archives (most cases, error message: "... is not
a valid archive") on i386-pc-solaris2.10 / sparc-sun-solaris2.10;

or extracts with wrong permissions and zero size on sparc-sun-solaris2.10 (but
only with archives generated on sparc-sun-solaris2.10).

Fix binutils configure script
Comment 4 Nick Clifton 2009-03-27 21:07:47 UTC 
Hi Niki,

  This was a nasty one.  In the end I tracked the problem down to the configure
script in the binutils directory which was behaving differently from the
configure script in the bfd directory, with the result that the two sets of
sources disagreed on the size of files that were being supported.  Most notably
this meant that the stat structure was a different size when being used by the
bfd library to when it was being used by the binutils programs.

  Please try out the uploaded patch and see if the problems are solved for you.
 (I have included a patch to the binutils/configure file so that you do not have
to run autoconf yourself).

Cheers
  Nick
