Hi Roland,

No - this is a completely different bug, and a nasty one too.

The issue is that the dll_symname string is used by multiple functions 
in ld/pe-dll.c, but it is only valid whilst the pe_process_import_defs()
function is active.  Unfortunately the code in ld/emultemp/pep.em calls
the function pe_find_data_imports() after pe_process_import_defs has
finished, and this function ends up calling down several layers to a
function that uses dll_symname.

I am not sure at this point, of the correct way to fix this problem.

Whilst I am thinking about it, do you have a test case that I can use
to reproduce the bug ?

Cheers
  Nick
