This bug seems to be fixed in gcc version 4.1.0 20050817 (experimental),
however it still seems to remain in gcc version 4.0.2 20050804 (prerelease).

Confirmed but note this is not a regression, -fsched2-use-traces is a new option in 3.4.0 and above 
and it has been failing since -fsched2-use-traces was added.
