The below error is seen when -ggbd3 is added to CFLAGS, but does not occur otherwise. I have tried gcc-4.4.4 on a native x86_64 build and gcc-4.4.4 cross build for mipsel.

Comment 2 Tor Andersson 2011-02-03 11:04:36 UTC

I cannot reproduce. I have tried both

gcc version 4.4.5 20100728 (prerelease) (Debian 4.4.4-8)

on amd64, and

gcc version 4.4.5 (Debian 4.4.5-8) 

on x86.
