"[One] need[s] the upcoming GDB to debug GCC 4.5 compiled code anyway, because older GDBs mishandle DW_CFA_restore_state which is now used all around in .eh_frame, otherwise backtraces really don't work." [1]
Thus one should document this in the GCC 4.5 release notes. GDB 7.0 will support this, for GDB 6.8 one can use the patches at [2].
