Thank you for your reply.

The '-g0' is needed because gcc-3.4 has a bug which will be triggered
when '-g1' is used to compile nptl (please see gcc-3.4 bug #260710 in 
the BTS). This gcc-3.4 bug is known to upstream since a while ago and 
has been discussed on the upstream gcc developers list. However, I 
could not find a better fix. 
This gcc-3.4 bug is not amd64-specific, it also occurs on i386.
