Same over here, after updating this morning (ca. 10:00 UTC), on  
m68k-next-nextstep3, so it's probably pretty generic:

(gdb) run tinfo.ii  -quiet -dumpbase tinfo.cc -g -g1 -O2 -O2 -O2 -W  
-Wall -version -fexceptions -o /usr/tmp/cc027905.s

Hope someone can make something out of this - it's C++, so my NIH  
alarm immediately closed down all relevant brain capacity ...
