I think that this might actually be a "feature" rather than a bug. What
appears to be happening is that the "DWARF error" message is being printed to
stderr, whilst the "0000ffff N .debug_info" message is being printed to stdout.
But somehow you are collecting both streams into your output file (which
should not be happening with just the ">" operator...) and the order in which
the messages are printed out is different bewteen the two compilers. This
suggests that the code sequences have been compiled slightly differently. But
basically both versions are doing the same thing and producing the same output.
It is just the synchronization between stdout and stderr that is different.
Cheers
Nick
