On feather, languages/c99 (et al.) fail with:
$ make
../../parrot -o src/CPP_PGE2AST.pbc --output-pbc src/CPP_PGE2AST.pir
*** glibc detected *** ../../parrot: double free or corruption
(fasttop): 0x0823e328 ***
running this through gdb, I get:

compilers/imcc/imcc.l:888 seems to be where it goes off the rails..
IANACP, but there seems to be several calls to 'free(valp->s)' in
that function that aren't careful about not freeing that pointer more
than once.
