I tried it. But when I compile it with -g, I cannot reproduce it from
the shell or from gdb. But if I call "make", it fails again.

I also use a UltraSPARC for this. I compile groff and then run
"sparc32 make" in the groff/doc source directory and it fails
with:

export GROFF_TMAC_PATH; \
sed -e "s;@VERSION@;`cat ../VERSION``sed -e 's/^0$//' -e 's/^[1-9].*$/.&/' ../RE
VISION`;" pic.ms \
| ../src/roff/groff/groff -p -e -t -Tps -F../font -U -ms -mwww >pic.ps
../src/roff/groff/groff: troff: Illegal instruction

All other input files works fine. Same for uic from qt2 and qt3: If
I try to debug it, it works. And there are only a few input files
for which it fails, most input files works fine.
