It looks like the latest coroutine changes have uncovered a bug; now I can't
get Parrot to build. Here's the relevant message:
gmake[1]: Entering directory `/home/chromatic/dev/parrot/compilers/pge'
/usr/bin/perl5.8.8 -MExtUtils::Command -e rm_rf
PGE.pbc ../../runtime/parrot/library/PGE.pbc

../../parrot pgc.pir --output=PGE/builtins_gen.pir PGE/builtins.pg
gmake[1]: *** [PGE.pbc] Segmentation fault
Going into compilers/pge and massaging the Makefile not to delete the
appropriate files gets me further. Now TGE has similar problems, and I get
back to:
$ ../../parrot ../../compilers/pge/pgc.pir --output=TGE/Parser.pir
TGE/Parser.pg
Segmentation fault
$ gdb ../../parrot
(gdb) run ../../compilers/pge/pgc.pir --output=TGE/Parser.pir TGE/Parser.pg
