Summary:                    gstrip seems to corrupt the syminfo elf section used
by the SUN linker
Description: 
Hi Maciej

It seems I found a problem with GNU strip while enabling direct binding on
gnomevfs2.
The GNU strip utility seems to corrupt the syminfo elf section where the
information are stored.

Details are below.

I fixed the problem in the package by making sure Solaris strip was used in
gnomevfs2 (which is normally the default) so it is not an urgent problem.
But it is probably interesting to take this issue upstream.

Before striping:

# ls -l ./gnomevfs-mv 
-rwxr-xr-x 1 yann csw 16336 Aug 26 09:10 ./gnomevfs-mv
$ elfdump -y gnomevfs-mv
Syminfo Section:  .SUNW_syminfo
     index  flags            bound to                 symbol
       [1]  DB               <self>                   .ld_double
       [2]  DB           [4] libc.so.1                printf
       [3]  N                                         _end
[...]


After striping with GNU strip:
$ ls -l ./gnomevfs-mv 
-rwxr-xr-x 1 yann csw 12580 Aug 26 09:15 ./gnomevfs-mv
$ elfdump -y gnomevfs-mv
gnomevfs-mv: .SUNW_syminfo: invalid sh_info: 0
gnomevfs-mv: .SUNW_syminfo: invalid sh_info: 0
gnomevfs-mv: .SUNW_syminfo: invalid sh_info: 0


The native strip utility doesn't have the same effect.
After striping with /usr/ccs/bin/strip:
$ ls -l ./gnomevfs-mv 
-rwxr-xr-x 1 yann csw 12636 Aug 26 09:15 ./gnomevfs-mv
$ elfdump -y gnomevfs-mv
Syminfo Section:  .SUNW_syminfo
     index  flags            bound to                 symbol
       [1]  DB               <self>                   .ld_double
       [2]  DB           [4] libc.so.1                printf
       [3]  N                                         _end
     [...]
