internal compiler error: in expand_debug_locations, at cfgexpand.c:3683

[Patrick Oppenlander <pattyo dot lists at gmail dot com>]

Hi,

I'm running into an internal compiler error when trying to build a 
powerpc project.

In the past when I've run into ICEs I usually submit the preprocessed 
source as part of the bug report. In this case I'm not sure what to 
submit as the error is occuring during the LTO link phase.

Running gcc with -v -save-temps results in the following output and a 
bunch of *.ltrans??.o files a ltrans.out file and a libgcc.res file. Are 
these of any use or do the original object files need to be included in 
the bug report?

Also, is there any other way to diagnose what's going wrong here?

Thanks,

        Patrick
