Also, http://homepages.paradise.net.nz/lparkes/pr/gcc-ice-1.txt
contains this error message with a few extra lines of
context. http://homepages.paradise.net.nz/lparkes/pr/bar.c contains
preprocessed C source that triggers this ICE when compiled with 'gcc
-c -O2
bar.c'. http://homepages.paradise.net.nz/lparkes/pr/gcc-ice-2.txt
contains the complete output from running gcc on bar.c

>How-To-Repeat:

Type make in pkgsrc/graphics/netpbm or run gcc -c -O2 bar.c. 

>Fix:

None.
