Hello there,
I just tried to compile the following illegal C++ code on a
i686-pc-linux-gnu box with the latest gcc 3.4 snapshot 20050128
char fred = ' ;
The compiler said
[dcb@localhost Alphasrc]$ ~/gnu/20050128/results/bin/g++ -c jan29a.cc
jan29a.cc:2: error: missing terminating ' character
jan29a.cc:2: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Here is a bit more detail, provided by valgrind

Yes, but I am not sure what is the best fix. Mark, shouldn't
cp_lexer_peek_nth_token always work, no matter how big the N is? I think it
could return NULL if N is too big, but segfaulting looks a little too much to
me.
