Hello,

you reported this bug against gcc 3.0? Would it be possible to check whether gcc 3.3 still has this 
bug in it? Or to reduce a testcase for other platforms? Thanks,

Dara

On the machine i used to report this - I now use gcc 3.4 CVS - I still use the
same patch, but I am no longer attempting to compile mozilla with gcc on this
platform.

However, I see no reason for why my patch is no longer needed, despite not
having a test case around to check anymore.

To clarify, if collect2 creates a temporary object for the purposes of
constructors etc - and -soname option is specified on the link line before other
objects - then things will break.
This is because the name after -soname generally ends in .so - and will be
recognised as an object. Also, because first_file will be set until an object is
actually found - the o_file will be inserted into the argument list before the
name associated with -soname.  Therefore ld will think the temporary object file
is the soname - and the soname is an object file needing to be linked.  Ld will
fail to find this object and die.
Basically, unpatched - collect2 knows nothing about -soname options and
correspondingly how to deal with -soname's argument.  My patch simply makes it
auto add the next entry, so as to ensure that the argument is passed togeather
with the -soname option.

If i understood the mechanisms which cause collect2 to create a temporary object
- then creating a testcase should be simple.  However i dont, and dont have time
to right now.

This should not be in waiting since the bug is there but not fixed yet.
