--- Comment #4 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> 2011-02-21 14:35:20 UTC --- Status update. I have more or less isolated the problem in list-read.c. I do not have an exact solution yet, but I am able to get the test case to work. I just need now to find the right place to make the tweak.
