OK, you hit the nail on the head with that one. gcc works fine until i
install binutils, at which point it breaks.

pre-binutils:

spicy-pickle:~ > ./hello 
Hello, world!
spicy-pickle:~ > echo $status
0

post-binutils:

spicy-pickle:~ > ./hello
Hello, world!
Segmentation fault
spicy-pickle:~ > echo $status
139
spicy-pickle:~ > sudo truss ./hello

bummer. here's what i'm doing. i'm building all of these packages:

autoconf automake bash bc binutils bison ddd diffutils enscript
fileutils findutils gawk gcc gdb grep groff gzip java2html less libtool
m4 make patch plotutils rcs sh-utils sharutils tar texinfo textutils
wget

make first, gcc second (bootstrap with sun cc 5.0), binutils last, and
everything else in the middle somewhere. /usr/local/gnu/bin is first in
my path, so everything except for make and gcc are built with
gcc/gmake/etc.

Is there some special trick to installing these packages? some
unwritten order you have to follow? i guess next i'll check what files
binutils is clobbering; one by one i ought to be able to track down
what file binutils is installing that's breaking gcc.

sorry to bother you guys with lame questions,

Jesse
