Hi,
as I now and then read binutils@ archives I saw that a 2.10 release is
near. Good :) As I pointed out some weeks ago, ld has problems with the
C++ symbols support in version scripts. In the branch, and in HEAD. It
segfaults for version scripts containing 'extern "C++" { bla }'
directives. This is due to a wrong yacc rule (patch for ldgram.y).
And it doesn't recognize '::' in those C++ symbols, due to too restrictive
LEX symbols definitions (second patch for ldlex.l). I hope it's not too
late for the branch, as I wanted to finally use a released version with
C++ version scripts :)
Ciao,
Michael.
