[Bug c++/19710] New: ice on invalid one line C++ code

[dcb314 at hotmail dot com]

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
