[Bug c++/18825] New: ICE in wv2

[steven at gcc dot gnu dot org]

cc1plus ICEs on the to-be-attached test case with any combination of 
options, on all targets I could try: 
 
t.ii: In instantiation of 'wvWare::PLCFIterator<wvWare::Word97::PCD>': 
t.ii:54513:   instantiated from here 
t.ii:47001: internal compiler error: Segmentation fault 
Please submit a full bug report, 
with preprocessed source if appropriate. 
 
Here's a bit of gdb output:
